a good r/o system will yield a tds reading of 0 to 5 ppm regardless of how many gallons its rated.
No RO system will get you 0 ppm. If they say that run there full of shit. But 5-12 ppm is good.
The gpd has nothing to do will how well it works. All should be the same. And as long as you get get a system that gives you more then what you need your going to be happy.
