Baylor, Texas A&M, U of Texas- Austin, or Texas Tech?

Okay I've gotten into Baylor and Tech, and I'm pretty sure I will get into the other two, but I'm wondering which one should I choose and why?, I am leaning very for Baylor but I haven't heard all that great of things about social life and student body. I am a very liberal person, I am also gay, I am not religious but, I was raised Christan and Muslim, (lol, I know, but my parents are divorced) so I have no problem with the Christian religion. Which dorm should I choose?, I would prefer to stay in the athletic dorms, but I don't know which one that is. And lastly, I am going to be a dentist, so I am majoring in biology, pre-dentistry or biomedical, it just depends on the college..
