I'd like to second Milton. I'm not sure it's got as much going on or as much of a distinct identity as Newton, but I like Milton a lot more. Btw, Buckminster Fuller grew up in Milton. I'm from Canton myself.

Also, if you're thinking more city, Quincy is worth considering. The schools aren't as good, but it's a city with more of a city vibe along Hancock St (though it's less happening than a small southern city like Savannah GA for example, tho that may be because Savannah is a college town).

Newton schools certainly produce lots of stars and high achievers. I've known a bunch. However, I think Milton is probably similar if not as notorious, and if anything I think it'd be nice to get away from the hypercompetitive vibe of Newton.
