There are different things to consider when deciding between the two.
Personally, between the two I like Texas Tech more because they are already established and well-known to be a good pharmacy school. UNT isn't necessarily bad, but they haven't graduated a class yet so it's hard to say if they'll be a good school or not.
If you go to TTU, then you can always come to the Dallas campus after two years even if you go to Abilene if you want to stay in DFW. I think they're both good, it just depends on which school you like more.
I personally loved TTU in Abilene, they are so friendly and welcoming, I was immediately won over but I'm actually hoping I get into UT Austin because I'd rather live there than Abilene which is my hometown, haha.
I hope that helps!
