My boyfriend just finished MS-2 at RWJ, so I can tell you some things about it. He is always very stressed, and just about everyone that I met there thought the first two years are incredibely difficult. This is not to say that med school will be a breeze elsewhere, but RWJ's first two years are, in my opinion, structured very traditionally and rather badly. I also find the academic building to be very gloomy, and I don't like how you'll be using the gym of the undergraduate campus and how the hospital is a 10-15 min. drive away. I also don't like that you have very limited options about which hospitals you rotate through 3rd year (i think there are about 3 hospitals). And finally, i'm from NJ as well, and I would really like to go live somewhere else for a while.
Personally, I chose UPitt over RWJ despite the tuition difference. Honestly, though, i'm not sure that I would have chosen Georgetown over RWJ, simply because I feel that the difference in rep and curriculum between the two isn't so great. However, if Georgetown and RWJ are your two choices, then you may well be better off going to G-Town for the experience at the very least.
