Not sure how you selected the list, but leaving Darden off is like trying to create a list of best sports cars and leaving off Ferrari.
I'll second Kryzak about UCLA. The location is among the best, the campus is awesome and the business school is nice as well. I looking out my window right now across campus and its awesome.
UCLA and Berkeley win in terms of weather, which is a huge factor. You just feel better when the weather is nice. Haas had nice buildings, but the interior accoutrements were low rent and things seemed pretty worn.
Darden doesn't have the weather of LA or SF, but it's a heck of a lot better than any of the other schools. The UVA campus is famous for its beauty and historical significance. The business school is new and first rate. The immediate surroundings are country-club-like and the the trees and blue ridge mountains are spectacular.
I think Stanford is nice, but to tell you the truth I don't rate it that highly. Maybe it's because I lived in the bay area for a 5-year stretch and there are just other places in the area that are a lot better.
Northwestern, it was OK but I'm not a fan of local weather or the city. Same applies to University of Chicago, but the campus location is 100000000% worse. I haven't seen the new building though, but you can't stay inside 24/7.
I like Michigan a lot, but Ross has the unfortunate problem of being right across the street from the law school. The law school is renowned for its beauty and has been used as the setting for many movies (for example A Beautiful Mind). The old business school building was beat up, but of course there will be a new soon. The biggest problem is that the weather really sucks. Sucks, sucks, sucks (not as bad as Chicago though). The place is overcast from October to March. Any day of sunshine is like a gift, even though it will still be freezing and snow and slush will be everywhere. Big contrast from Westwood for sure.
Wharton was huge and impersonal, and has too many undergrads crowding the building. The rest of the campus is alright, but the first time I visited, some guy was shot in a phone booth on the edge of campus, so they've got that going for them.
It's been years since I've visited Harvard, even longer since I visited Yale or Cornell. None really left that much of an impression, though I recall a student at Yale telling us that walking around a night can be dangerous. Never been to Tuck.
