Gerber Avalanche versus Toto Drake

My son defecates about 1x / 3 days with predictable results. Ancient Cadet not up to the task. Bathroom is VERY close to MY bedroom, so think pressure assist probably not the greatest option. Local plumber recommends the "Avalanche" by Gerber, says this is "best" he's used. But can find no reviews or other info on this model. Anyone here have any experience with this model? He also likes the "Drake", has installed plenty but prefers the Avalanche now ....

Any info appreciated!

I use A LOT of the new Gerber toilets . They really are VERY good! Don't have the specific "grams of crap" removed in each flush but I've been at this 26 years and haven't found a better 1.6gal flusher !

The Drakes are tried & true too. Go with the look you like ,,,, either toilet will be great.

Just a professional opinon .
