I think that as far as the EMBA programs go, these are all pretty comparable, and I'm not sure that any would be better than the others. Course structure and even curriculum are both relatively similar among the four.

I suppose I would make my decision on the following factors:
- cost/availability of financial aid: maybe one school is offering you a better package?
- alumni satisfaction: try to connect with alum and ask them about the programs as well as how they are doing post-EMBA
- general feel: how the schools have treated you during the application cycle says a lot about their culture and outlook.

I like Birmingham, personally. I know you'd only be there for week long modules but it's a cool city, with a lot of activity.
