Congratulations! Great choices! You can’t really go wrong with any of them. I’d have been happy to attend any of them (and did attend one).
Wake is terrific academically, and there is a large Greek presence, and social life tends to center around Greek parties. Not everyone participates, and I’m sure lots of students who love the school don’t, just saying that is a large part of the social dynamic. It would definitely have the most big-time sports on your list, and several teams (football and soccer) have done very well in recent years.
CWRU is unique on your list as a STEM school, where a large % of students are STEM majors. So that would be very different than at Middlebury or Wesleyan. It seems like it as a reasonable social life, and the Greek system is not as prominent as at Wake. Sports is definitely not as big-time as at Wake, which has the most robust NCAA athletics of the schools on your list. There are good places for students to go on Euclid Ave, which splits the campus, and in Little Italy, which is just a couple of blocks off campus.
William and Mary is excellent for CS also. It has 6500 undergrads, larger than all on your list except Emory, I believe. Sports are about middle of the pack in terms of colleges. Nice small/mid-size football stadium, good basketball team. Nice environment, with a fair number of things to do adjacent to campus.
Middlebury and Wesleyan are both outstanding New England LACs. Wesleyan is a little bigger if I recall correctly. Sports are smaller at both schools. We were never around for games, so I’m not sure about student interest/enthusiasm.
Emory is outstanding. The main campus is beautiful. When we visited, we did feel that it did not have big-time school spirit. Someone asked about sports, and rep in info session said students interested in sports usually go over to Georgia Tech for the games.
I’ve been to all these schools and know most of them very well (immediate family have attended/are attending three in recent years). I really like all the campuses. CWRU is an urban campus with Euclid dividing the old Case Institute of Technology and Western Reserver College campuses (the schools merged). The area is pretty nice, with some rougher neighborhoods a few blocks away. The main Emory campus is in a suburban area (did not go to Oxford), Wesleyan too. Middlebury and William and Mary are in small towns, a little more to do in Williamsburg. Wake is a fairly isolated campus, with nothing that students can easily walk to, but is close to Winston-Salem, which has a fair amount to do.
Good luck!
