I agree, it always makes sense to see what's out there. Upstate hasn't made the rankings recently, but US News ranks more on the amt. of research funding than the level of student satisfaction, debt, and match success. Upstate now is really a nice place for students -- a new auditorium, a beautiful library, renovated classrooms, a new $20 million institute for research and teaching space... and the hospital is making plans to expand in the next several years.
It also depends on where you might like to end up after medical school. About half of our class is from the NYC area, and many want to return there for residency... so we match many people to NYC and the programs know us well. If you prefer the Boston area, then obviously Tufts makes more sense...
