it seems there's the big three (from what i understand)-
sinai, columbia, cornell...apparently they are all very similar in terms of volume, diversity and quality but vary in their general "feel" and percieved competetiveness (ie sinai is not "ivy").
i have buddies at 2 of the 3 and hear the same complaints and accolades even though the programs are different (e.g there's not enough ancillary care but the hours aren't bad, the cases are great, etc.) and both think they're at the "best" program in NYC...which i think is a good thing because one would hope to feel that way about their program
