Honestly I always thought it was A&M>SA>Houston but maybe I'm just salty I didn't get into Houston
On a real note I chose A&M over SA because I like the city of Dallas more (and have family here). By the time you get in (assuming you're a pre-dent) you will be doing all your clinical work in the new building so both will have new facilities, but honestly if you choose a school because of their new shiny building that's dumb.
If you want to know more message me!
