Having had the Cadet 3 for well over a year now, I have come to the conclusion that it is fantastic toilet for a DIY homeowner.
Less so for a plumber, which is why they push the Totos.
The problem with a lot of Cadet 3s is that they require small adjustments, mostly to the chain which could cause plumbers lots of annoying call-outs. For a DIYer, it's much less of a headache.
So, if I wanted a plumber to install a toilet and I did not want to touch it again, Toto.
If I wanted to do it myself, save a few bucks and didn't mind a few adjustments on the way until she works just perfect (then you do not need to touch it again), I'd go Cadet 3 again.
