I can't offer specific evaluations of any those schools, but in my opinion, the things you should be considering most are
1) Do you like the person (or people) who would be teaching you composition? Find out who teaches at the schools and try to find recordings of their music. While any teacher will certainly work with you to help you develop your own style, it will help if s/he has a style that you're interested in imitating. If you have the opportunity to visit any of the schools, definitely try to arrange a meeting with the composition faculty.
2) What are the opportunities like for getting your work performed at the school? This can be difficult to judge by just looking at websites, etc. Talking to faculty can be helpful, but they'll portray things in the best light possible -- ideally, you would want to talk to a current student about it.
3) Finances are important and should be factored into the decision.
