Depends on your situation, ie, if you've got anything holding you to one location which would make the military more difficult. Or more importantly, which school did you like best? I got accepted to Columbia but I turned them down because I felt that when I went around for my interviews, I just felt like I fit with Pitt better, so I decided on going there. Also, I've shadowed with a number of dentists who did the military route and they all say it's the best choice they've ever made. You should really pick a school on your personal feelings about it, and not just the name.
Good luck!
