Keep in mind that Robert Wood is mostly state students, a lot of them are already from the area (a lot from Rutgers especially). MCW seeems to have a more diverse student body.
As far as reputation- Robert Wood is ranked for primary care medicine. Also another good thing is they have one of the only cancers centers in the U.S. as well as a brand spankin new children's hospital.
The medical school where you do your first two years is in Piscataway which is a drive (about 2 miles) from the hospital and the clinical academic builiding in New Brunswick.
As far as New Brunswick is concerned--it's really not that great. Rutgers is right next to the med school if you like having a really large public school next door. Yeah, it's kinda close to the city but still a drive (about 45 min or an hour train ride).
I don't know that much about the midwest but I think people there are more laid back---you'd probably have more fun at MCW than Robert Wood, which might be a little more cutthrought.
I picture you as a ski bunny right? Midwest might be better with more outside stuff and laid back attitude.
Also keep in mind that robert Wood will grant you in-state tuition (cheap!) in your FIRST year of Medical schhol as long as you move in a little before school starts and get a New Jersey License and a couple of other things.....
Maybe you should check it out and see what you think.....my gut tells me that you would like MCW better but what the hell do I know
Well good luck.....
