Hey, I don't have time to write out full reasons, but as a graduate of the G-town SMP, I thought I'd throw out a quick opinion. I'll do my best to come back later and explain!
I'd go with Cincy. Truth is you can't go wrong with either. They are both the two best programs, in my opinion.
I'd pick Cincy over G-town for these reasons:
1) You establish Ohio residency while in the program.
2) Smaller class size means more face time with admin and teachers.
3) Most important reason for me, is simply that I would have rather lived in Cincinnati than DC. (Cheaper, etc.)
So, I want to reinforce, that you can't go wrong, and that i LOVED my time at Georgetown. I was just really impressed with U Cinc when I interviewed for their medical school. I'll try to come back and post more later!
