Let’s Make Long Story Short: If you want the best value for performance, efficiency, and affordability, go with the Waterdrop G3P600. It uses 600 GPD filtration (great for most homes), includes a UV sterilizer, smart TDS monitoring, and tankless design but what really steals the show is the ultra-low wastewater ratio (2:1) and easier filter replacement, all at a better price.
The G3P800 is stronger in raw output with its 800 GPD flow rate and slightly better waste ratio (3:1), but it’s more expensive and overkill unless you have a large family or heavy daily usage. Choose Waterdrop G3P600 if you want premium-level filtration at the best value—it’s the smarter pick for most users.
