The Short Answer
For most kitchens, the LG LDTH555NS delivers the strongest value: the cheapest capacity at $46.66 per place setting, aggressive QuadWash Pro cleaning, and a complete cycle in 1 hour. The Bosch 800 SHX78DM5N instead prioritizes considerably quieter 42dB operation and zeolite drying that finishes plastics nearly dry.

You want a connected dishwasher you load, start remotely, and forget entirely. The premium built-in category resolves into a two-brand argument, and the manufacturers approach it oppositely. LG prioritizes wash power and velocity: QuadWash Pro jets produce considerably more cleaning power, alongside a genuine 1-Hour Wash & Dry. Bosch prioritizes dry, quiet operation: zeolite CrystalDry actively dehumidifies plastics, and the 800 Series achieves a class-leading 42dB.
This guide evaluates all four Amazon configurations on one weighted composite, the SHE Premium Dishwasher Value Score, whose heaviest factor remains wash-and-dry technology. The most affordable unit, the LG LDTH555NS, calculates to $46.66 per place setting. Compared to that, the Bosch 800 commands the highest cost per setting yet delivers the only 42dB rating and zeolite drying available here as of June 2026. Affordability versus polish ultimately decides this matchup.
Best Overall Value: LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher
LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher
The LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher earns the top composite of 8.7 on the SHE Premium Dishwasher Value Score. That weighted figure translates into a concrete outcome: at $46.66 per place setting it represents the cheapest capacity available here, so the affordability factor maxes out completely. QuadWash Pro produces multi-angle high-pressure jets that deliver considerably more cleaning power, while heated Dynamic Heat Dry handles glassware and ceramic competently. Consumer Reports independently rates the LDTH555NS within its dishwasher evaluation program for wash performance and reliability.
The differentiator is velocity. A genuine 1 hour wash-and-dry cycle clears a complete fifteen-setting load rapidly, and the adjustable third rack plus nine wash cycles contribute meaningful flexibility. Rated at 46dB, it operates quietly enough for an open-plan kitchen, though it registers four decibels above the Bosch 800 SHX78DM5N at 42dB.
Compared to the Bosch SHX78DM5N 800 Series Smart Dishwasher, the LG substitutes a marginally louder, heated-dry finish for a substantially lower cost per setting and a faster cycle. For the majority of households, that configuration favors the LG decisively.
What We Love
- Lowest cost in the set at $46.66 per place setting ($699.97 for 15)
- QuadWash Pro jets rate 38% more cleaning power than standard LG arms
- A genuine 1-Hour Wash & Dry cycle, rare at this price
- Full LG ThinQ Wi-Fi for remote start and cycle monitoring
What Could Be Better
- Heated Dynamic Dry trails Bosch zeolite on plastics
- Rated 46 dB, four decibels louder than the Bosch 800
- No steam cycle; the LDTS5552S adds TrueSteam for more money
The Verdict
If you're outfitting a busy kitchen and want hard cleaning without overpaying, the LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher fits the brief without compromise. The 8.7 reflects what most buyers actually weigh: the lowest $46.66 per place setting, QuadWash Pro power, and a 1-hour cycle. You give up four decibels and zeolite drying to Bosch, but for most homes this is the path of least friction.
Best for Quiet + Dry Plastics: Bosch SHX78DM5N 800 Series Smart Dishwasher
Bosch SHX78DM5N 800 Series Smart Dishwasher
The Bosch SHX78DM5N 800 Series Smart Dishwasher earns a composite of 8.4 on the SHE Premium Dishwasher Value Score, second overall but the unmistakable performance champion. Its zeolite CrystalDry constitutes the configuration's only active-mineral drying: Reviewed determined even plastics emerge with barely a bead of water, whereas every heated dryer here leaves them measurably damp. That outcome maxes the heaviest factor in the composite.
Quietness produces the other decisive win. Rated at 42dB, it operates as the quietest of these four units, and Reviewed characterized the 800 line as one of the quieter models, with laboratory evaluation landing approximately 99.97% clean. PrecisionWash with PowerControl, sixteen place settings, and a well-designed Home Connect application establish a genuinely premium machine.
Compared to the LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher at 46dB, the Bosch trades a considerably higher $81.13 per setting and no rapid cycle for demonstrably quieter, drier results. That configuration justifies itself exclusively when quiet operation and dry plastics dominate your priorities.
What We Love
- Zeolite CrystalDry leaves even plastics with barely a bead of water
- Rated 42 dB, four decibels quieter than either LG
- PrecisionWash scored roughly 99.97% clean in lab testing
- Home Connect app is well-designed for remote start and diagnostics
What Could Be Better
- Highest cost in the set at $81.13 per place setting
- Fully integrated panel needs a precise flush cabinet cut
- No 1-hour wash-and-dry to match the LG LDTH555NS
The Verdict
If you've clocked the open-plan kitchen and the daily Tupperware re-drying you hate, the Bosch SHX78DM5N 800 Series Smart Dishwasher is a sensible pick for that setup. The 8.4 reflects performance you hear and feel: the only 42dB rating here and zeolite CrystalDry that finishes plastics nearly dry. You pay the most per setting, but for quiet and dry, no need to overthink it.
Best for Steam Sanitizing: LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher
LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher
The LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher earns a composite of 8.0 on the SHE Premium Dishwasher Value Score, the feature-loaded LG. Its differentiator is TrueSteam, which delivers an NSF-certified 99.999% bacteria reduction on the Steam cycle, layered over QuadWash spray arms and heated Dynamic Dry. Consumer Reports independently rates the LDTS5552S within its dishwasher evaluation program for wash performance and reliability.
The flexibility remains substantial: an adjustable third rack, fifteen place settings, and complete LG ThinQ Wi-Fi for remote start and cycle download. Rated at 46dB, it matches the LDTH555NS for acoustics, registering four decibels above the Bosch 800 at 42dB.
Compared to the LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher, this configuration adds steam sanitization but commands $564 more, calculating to $84.27 per setting, the highest figure here. Unless you specifically require steam, the more affordable LDTH555NS covers identical QuadWash and Wi-Fi territory.
What We Love
- TrueSteam delivers NSF-certified 99.999% bacteria reduction
- QuadWash spray arms plus heated Dynamic Dry clean thoroughly
- Full LG ThinQ Wi-Fi smarts, same as the LDTH555NS
- Adjustable third rack and 15 place settings for flexible loading
What Could Be Better
- Highest cost per setting in the set at $84.27
- Rated 46 dB, four decibels louder than the Bosch 800
- The cheaper LDTH555NS covers most needs without steam
The Verdict
If you're sanitizing baby bottles or running an allergy household, the LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher checks the boxes that matter for that situation. The 8.0 reflects a feature most buyers skip: TrueSteam's NSF-certified 99.999% bacteria reduction on top of QuadWash. At $84.27 per setting it is the priciest here, so you'll be well-served here only if steam is on your list.
Budget Bosch Badge: Bosch SHE43DM5N 300 Series Smart Dishwasher
Bosch SHE43DM5N 300 Series Smart Dishwasher
The Bosch SHE43DM5N 300 Series Smart Dishwasher earns a composite of 7.6 on the SHE Premium Dishwasher Value Score, the value Bosch. At $49.94 per place setting it represents the second-cheapest unit here, and it carries the Bosch reliability reputation. But it is emphatically not a discount 800: it employs condensation PureDry drying with no active heat, so Consumer Reports and owner reports indicate plastics may require air-drying afterward.
It also operates as the loudest unit, rated at 48dB, and a tighter interior configuration caps usable top-rack height. PrecisionWash nevertheless cleans competently across sixteen place settings, and Home Connect enables remote monitoring and remote start. Reviewed's best-Bosch evaluation positions it as the value tier of the manufacturer's range.
Compared to the Bosch SHX78DM5N 800 Series Smart Dishwasher at 42dB, the 300 abandons zeolite CrystalDry, accumulates six additional decibels of operating noise, and conserves meaningful money. It competes fundamentally on the badge and affordability, not on outright performance.
What We Love
- Second-cheapest at $49.94 per place setting ($799.11 for 16)
- The Bosch badge and reliability reputation on a budget
- Adjustable third rack and 16 place settings of capacity
- Home Connect Wi-Fi for remote monitoring and start
What Could Be Better
- Condensation PureDry, not zeolite; plastics may need air-drying
- Rated 48 dB, the loudest of the four units
- Tighter interior caps usable top-rack height
The Verdict
If you want the Bosch name and reliability reputation without the 800's price, the Bosch SHE43DM5N 300 Series Smart Dishwasher lines up with what you actually need. The 7.6 reflects an honest value tier, not a discount 800: at $49.94 per setting it is cheap, but you accept condensation drying and a 48 dB rating. For a budget Bosch buyer who knows that trade, no need to overthink it.

(WashDry Tech ร 0.28) + (Quietness in dB ร 0.22) + (Rack & Cycle Flexibility ร 0.18) + (App & Diagnostics ร 0.12) + (Price Per Place Setting ร 0.20)Score Factors
- WashDry Tech (28%)The strength of the wash system plus the drying method, the axis buyers care about most. Bosch zeolite CrystalDry, which heats a mineral to actively dry plastics and leaves barely a bead of water, scores a 10; LG QuadWash plus TrueSteam NSF 99.999% sanitization scores 9; LG QuadWash Pro with heated Dynamic Dry scores 8; Bosch 300 PrecisionWash with condensation drying, where plastics may need air-drying, scores 7. Scored from verified spec sheets and registered-outlet drying verdicts from Reviewed and Consumer Reports.

The Bosch 800 at 42 dB is the quietest here; both LG units sit at 46 dB; the Bosch 300 at 48 dB is the loudest. Corroborated by Reviewed's note that the 800 line is one of the quieter models.
- Rack & Cycle Flexibility (18%)The third-rack design plus cycle and option breadth. All four carry an adjustable third rack. The LG LDTH555NS adds a 1-Hour Wash & Dry on top of 9 cycles, scoring 9; the LDTS5552S adds TrueSteam, scoring 9; the Bosch 800 third rack with PowerControl scores 8; the Bosch 300 third rack, whose tighter interior caps top-rack height, scores 7.
- App & Diagnostics (12%)Smart-app capability and remote diagnostics. Bosch Home Connect, with remote start, cycle monitoring, and a well-designed app per Reviewed, scores 9; LG ThinQ Wi-Fi, with remote start, cycle download, and Proactive Customer Care diagnostics, scores 9; the Bosch 300 Home Connect, with fewer programmable extras than the 800, scores 8. All four are Wi-Fi connected.
- Price Per Place Setting (20%)The live Amazon price divided by rated place-setting capacity, inverted so a lower cost per setting scores higher. The LG LDTH555NS at $46.66 per setting maxes the factor; the Bosch 300 at $49.94 is close behind; the Bosch 800 at $81.13 and the LG TrueSteam at $84.27 cost the most.

Ecosystem Fit: ThinQ, Home Connect, and Voice
All four dishwashers are Wi-Fi connected, so ecosystem compatibility rarely determines this matchup. The two LG units operate LG ThinQ; both Bosch units operate Bosch Home Connect. Each application handles remote start, cycle monitoring, and notifications, and all four integrate with Alexa and Google Home for voice status verification. Reviewed characterized the Bosch 800's Home Connect application as well-designed, and LG ThinQ enables Proactive Customer Care diagnostics that identify faults before a service appointment.
The genuine differentiation resides in the hardware, not the protocol. The Bosch 800 pairs a 42dB wash with zeolite CrystalDry, while the LG LDTH555NS counters with a 46dB rating, QuadWash Pro, and a 1 hour cycle at a substantially lower cost per setting. Functionally the two applications are equivalent, so configure the comparison around your floor plan and your priorities, not around the smart-home badge. Both ecosystems are mature as of June 2026, and neither becomes the incorrect purchase on application capability alone. The SHE Premium Dishwasher Value Score consequently weights drying technology and quietness considerably above ecosystem compatibility, because that weighting produces the recommendation buyers actually need.

When NOT to Buy
A premium connected dishwasher is not automatically the appropriate decision. If your kitchen operates compactly or you rarely accumulate a complete load, a more affordable connected unit from our Best Smart Dishwashers 2026: Wi-Fi & Quiet Picks hub washes identical dishes for considerably less expenditure. The 42dB rating and zeolite drying become capability headroom you financed and never genuinely utilize. If your apartment provides only an 18 inch cabinet aperture, none of these full-size 24 inch units physically installs, so a compact configuration becomes the necessary alternative. Match the expenditure to your kitchen architecture and your habits, and reserve the premium tier exclusively for situations where a simpler machine cannot genuinely satisfy the requirement.
Frequently Asked Questions
LG vs Bosch โ which should I actually buy?
For most kitchens, buy the LG LDTH555NS: at $46.66 per place setting it is the cheapest here, QuadWash Pro rates 38% more cleaning power, and a true 1-Hour Wash & Dry finishes fast. Buy the Bosch 800 SHX78DM5N instead if a quiet 42 dB wash and zeolite CrystalDry drying that leaves plastics nearly dry matter more than price. The tradeoff is value and speed versus quiet and dry; your priorities decide it.
Does Bosch CrystalDry really dry plastics better than LG's heated drying?
Yes, per Reviewed's testing of the Bosch 800 line. Zeolite CrystalDry heats a natural mineral that pulls moisture and releases heat, so even plastics come out with barely a bead of water. LG's heated Dynamic Dry warms the air instead, which works well on glass and ceramic but, like all heated drying, leaves plastics damper. If hand-drying Tupperware is your daily annoyance, the Bosch 800's zeolite system is the meaningful upgrade here.
Is the Bosch 300 Series just a cheaper 800?
No. The Bosch 300 SHE43DM5N is a value tier, not a discount 800. It drops to condensation PureDry drying instead of zeolite CrystalDry, so plastics may need air-drying. It is rated 48 dB versus the 800's 42 dB, making it the loudest of these four, and its tighter interior caps usable top-rack height. It competes on the Bosch badge and a low $49.94 per setting, not on the 800's drying or quietness.
Is LG TrueSteam worth $564 more than the LDTH555NS?
Only for steam-sanitizing households. The LG LDTS5552S adds TrueSteam, an NSF-certified 99.999% bacteria reduction on the Steam cycle, on top of QuadWash, but it costs $84.27 per setting versus the LDTH555NS at $46.66. That is $564 more for one feature. If you sanitize baby bottles or run an allergy household, the steam is worth it. Otherwise the cheaper LDTH555NS covers the same QuadWash and Wi-Fi ground.
Which of these dishwashers is the quietest?
The Bosch 800 Series SHX78DM5N, rated at 42 dB, is the quietest of the four. Both LG units sit at 46 dB, four decibels louder, and the Bosch 300 at 48 dB is the loudest. For an open-plan kitchen where the dishwasher runs while you are nearby, the 800's 42 dB rating is the clear pick, and Reviewed described the 800 line as one of the quieter models on the market.
Can I start and monitor all four from my phone?
Yes. All four are Wi-Fi connected smart dishwashers. The two LG units use the LG ThinQ app and the two Bosch units use Bosch Home Connect, and each handles remote start, cycle monitoring, and notifications. All four also integrate with Alexa and Google Home for voice status checks. Reviewed called the Bosch 800's Home Connect app well-designed, while LG ThinQ adds Proactive Customer Care diagnostics that flag faults remotely.
Bottom Line
Get the LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher if you want the best value, hard QuadWash Pro cleaning, full Wi-Fi, and a 1-hour cycle for a busy kitchen.
Get the Bosch SHX78DM5N 800 Series Smart Dishwasher if you run an open-plan kitchen, hate re-drying plastics, and will pay for a 42 dB wash and zeolite drying.
Get the LG LDTS5552S QuadWash TrueSteam ThinQ Dishwasher if you sanitize baby bottles or run an allergy household and specifically want NSF-certified steam sanitizing.
The right call for most kitchens is the LG LDTH555NS QuadWash Pro Smart Wi-Fi Dishwasher at $46.66 per place setting โ the cheapest capacity here, with QuadWash Pro and a 1-hour cycle. For quiet and dry plastics, the Bosch SHX78DM5N 800 Series Smart Dishwasher wins with 42 dB and zeolite CrystalDry. Skip the premium tier if your kitchen is small or your cabinet gap rules out a full-size 24-inch unit โ a compact model does the job for less.
