Were you accepted to all of them? Go Western lol.
seriously, all have different disadvantages and advantages.
Did you compare cost, retention and placement after graduation? Have thought about your specialty?
Which schools are more established. The one in San Antonio just started which is pretty exciting, big emphasis on primary care, new school growing pains (only 70% the students passed the first semester).
The most important thing is what makes you comrtable, because that will be your home.
Western is 55k+
UIW is 50k+
azcom is 65k+
KCU 45k+
I used the school ranking websites for cost, double check the school's website
