Which school should I pick if I can afford them all?

If you were my student, I would say go to the school where you feel the best “fit”. Size of school can be significant for some students. UM is an awesome school, but it is large. The smaller schools might fit your personality better. Given your financial picture, I wouldn’t worry as much about the cost. In the long run, you probably can’t make a wrong choice here. Your options are all good.
