Toto Drake Questions

I see a lot of recommendations for the Toto Drakes but their website shows 16 different models. Can someone recommend a good round-bowl model/s?

Are the round bowls as good as elongated?

What is "ADA"?

Thanks!

Go enlongated, you'll never go back.

ADA = American Dental Association
ADA = American Diabetes Association

or

ADA = Americans with Disabilities Act Which means a taller toilet.

CST743S, round front. 14.5" high bowl.
CST744S, elongated
CST744SG elongated with CEFIONTECT

CST744SL, elongated 16.5" high bowl.

Performance wise, they are fairly similar.
Anything over 500 grams is overkill.
The average person is "rated" at 250 grams.
