The Dalton works fine.
I'm surprised I don't sell more.
It works better then the Kohler Cimarron, but for less money.
Most of the time, because of a previous bad experience with something else, my customers buy the Drakes.
I have a few that always get the Dalton.
The Drake does have a better trapway, and the 3" flush valve. So yes, that is the top banana.
But not everybody needs that.
If cost is a factor, you may want to go with the Dalton.
