I don't know much about Tulane, but I posted this when someone else trying to decide asked me why I liked MSSM so much:
In addition to a great part of NYC (better than Cornell, Columbia, Downstate, or Einstein in my opinion) and P/F, I also liked:
1. The students - I got the overall best feel from the students at MSSM. To people who say you can't tell anything from the students because every school picks the happiest students to give the tours, I disagree completely. You can tell when people are being phony - and I talked to maybe 10 students throughout the day, and all of them had great things to say. The one negative thing I heard was that one student wished that MSSM had the same kind of name recognition as Cornell or Columbia. I don't give a damn about that (see the match list above - the match is great). Also, compared to Einstein, there seemed to be fewer married students (who are more likely to go off and do their own thing), which is good because I would like to be with as social a group of people as possible.
2. The hospital is great - so not only do you get great experience third and fourth years, but you have a better chance to get residencies at Mount Sinai hospital.
3. The international medicine opportunities - this is something I am definitely going to do probably the summer after first year and some time in third or fourth year. If you check MSSM's website, they have a huge range of opportunities - much more than most other schools. Particularly, they have a great program with Emory called MEDICC, which arranges medical internships in Cuba (particularly interesting to me).
4. The curriculum, etc. is geared towards helping students, not making them jump through hoops (unlike their Admissions office, which is still making us jump through hoops ). An example of how the school looks out for its students was from a student I talked to who said MSSM gives students time off (a month?) to study for the boards.
