Toto Drake vs. Dartmouth: the same or not?

I wan't an ADA-approved toilet and the supplier my plumber uses carries Toto's. Very impresssed with what I've read here. Two that look good from Terry's list are the Drake and the Dartmouth. From the specs, the guts of the toilets look the same. Does the outside appearance make a difference somehow? I prefer the look of the Dartmouth for my bathroom, but working well is my number 1 criterion! The Drake is number 1 on the list. Is the Dartmouth as good or not? There are no consumer reviews and I think it might be a newer model. Thanks for any help out there!

All of the Toto with G-Max are similar in performance.
That being the case, the only real difference between the Drake and the Dartmouth is the style.
