Physical attractiveness is in the eye of the beholder. Something like that probably requires you to visit Tufts and Emory in person.
Tufts is in a part of Boston that’s not that close to Cambridge where Harvard and MIT are located. Unless you’re willing to put up with a decent commute on the intracity train there (which includes waiting for said train to arrive at your stop), your social life won’t revolve around Cambridge (Harvard/MIT) if you’re a Tufts student. At least that’s what my friends tell me.
On the other hand, Georgia Tech is relatively close to Emory and connected by a free, convenient campus shuttle that runs a lot especially on the weekends. Students who want it can frequent Georgia Tech’s social scene as well as Emory’s.
