I am doing my MA at the University of WYoming. send me a message if you have any questions.... but I assure you, you will love it. Even though, it may not be Harvard, there is a lot of funding, awesome professors, and the head of the department gets an impressive list of people our here (who will have roundtables with students).
Well, firts of all congratulations. I would try to have a chat with both professors (if you are in Germany, perhaps over the phone or Skype) and see who you like best. I think Sarah Bush is a great person to work with, I attended a conference where she went, I was quiet impressed (but Middle East is not really my field).
I applied to both schools as well. I think Syracuse is better if you are focussing on security, and Temple is better if you do economic stuff. Also if you are an Europeanist Temple may be better because at Syracuse one is about to retire and the other is quiet inexperienced.
