I would say "NOT BRUMBY!" unless you're in a sorority or you like that type of all-girls environment.
I know people who love Creswell, but I think the room's are a bit smaller than Russell. Not sure about that though. Just by talking to people in the Freshman high-rises though, I'd say the general consensus is that Russell is the best. In my opinion, out of all the dorms possible for Freshmen to live in, O-House is hands-down the best. But maybe it's just because I love it so much. Affordable, near its own dining hall (the second best, next to ECV, in my opinion) and no community bathrooms. If you like lots of activity though, choose a high-rise. O-House is kind of quiet because there are upper-classmen who are over the wild freshman, newly independent stage
