lauren, I think that at the undergrad level, finding a school with diversity in student works, and openness to whatever you want to write, is the most important thing, and your post reflects that priority. At the grad level, the decision is different and aesthetic fit is key.
I think that conservatories are more preprofessional, and sometimes universities have an almost research attitude toward composing, so you get different emphases at different places.
If we knew whether you wanted a BM or BA, what your academic interests are, and if they are important to you, and what your financial situation is, we could be more specific in suggestions. Also, whether you are interested in orchestral work, chamber ensembles, as well as electroacoustic work, multi-media installations, film scoring or other specific areas.
