another cornellian here,
animosity?
haha.. when some of the strongest residents who are teaching on your 3rd year clerkship or 4th year Sub-I are from Columbia, or for that matter from Temple, or NYU, or Cornell, or Wash U, or a Qatari who went to a Russian Med school (this guy was awesome), it's hard to have animosity to any med school. Everyone is so inbred at the clinical level, seriously! Don't forget that. 🙂
really the question is where do you want to live for the next four years and have the best quality of life. you'll get great training on the medical side pretty much anywhere so long as you are pro-active, work well on a team, and are conscientious. remember, med school is pretty much a general medical education vs. residency, which is much more specialized (the differences can be quite large between residency programs). in the end, pick the place you'll be happiest at. a nice reputation is fine, but if you're miserable, that's a whopping huge amount of sweat, time, and dinero you're spending!
good luck,
MS4 and 5 months counting.... hallelujah!
