Both areas are pretty diverse and great people to meet. You’re also a <2 hour train ride to NYC from NHV.

I’d honestly be less concerned about the social aspect and more career. If either is better for career, go there.

I’d rather live in NHV because the winters are easier, there’s more outdoors options nearby, and I prefer New England. But otherwise, I don’t have any other strong reasons. They both can be great.
