If you have the money, State College PA is amazing for families.

Pros: you can get to anywhere in town within 15 minutes, lots of amenities, decent variety of shops, good nature nearby, great schools

Cons: high COL, high property taxes, large student body (Penn State)

Near philly, MontCo and Bucks County are nice. I spent 5 years in Skippack, that was a wonderful area.
