Read the stuff about Columbia and Cornell on this board. Cornell gets high ranks cause of its housing and then since the housing is so close, you get called in all the time. To top it off, a department in flux. Columbia - just do a quick search on this board to see what residents are going through, not good. The Harvard programs (MGH, BWH, BID) all have their pluses and minuses, especially the Harvard name, and there are some differences to how the residents are treated. With any of these, you probably can't lose. Mt Sinai and NYU not academic places with no name recommendation - the people posting are obviously from New York. Between Yale and BID, the answer is pretty obvious - BID. For starters - which eliminated it for me, Yale is in New Haven (not the safest place).
