Chapel Hill does not strike me as the great outdoors…you have to leave the area for that sort of thing.
UNC is a very spirited school. Greek life is there but not huge. You can attend concerts, go out to eat with friends, join clubs ( they are pretty active), volunteer, attend lectures, etc. The town is connected to the campus and the area is usually pretty busy. You will meet students from all over despite 18% OOS…but it’s a N.C. public university and lots are from N.C. That being said…you will find a diverse group.
NYU is an urban school…not a traditional campus. The overall feel will be different. NE has the coop …I have been told that once students go on coop you don’t see much of them. When we visited NE one of the students told me that it was very hard for her to adjust to coop. Everybody is different and you might love it.
Maybe somebody can discuss Tufts.
