Toto toilets - commercial vs residential

[cpmm]

I am remodeling 3 bathrooms and have been investigating toilets. I definitely want Toto toilets. My contractor can get me Toto commercial toilets - model CST 704 (gravity fed). My other option is to purchase residential toilets - either Drake (w/ G-Max flushing system) or Promenade (gravity fed). I have two questions - what is the quality of the commercial CST 704 vs the residential systems? For appearance I really prefer the Promade toilet - any thoughts on Promenade vs my other two choices?

Toto G-Max and PowerGravity toilets are better than any of the other Toto toilets added together!

The Promanade and the CST704 are not favorites of mine.
Too much splash and too shallow a bowl.
The G-Max and the Power Gravity models work better.

A model priced between those mentioned that I like is the Toto Dalton.
