I live 30+ miles north of Boston, on the New Hampshire/ MA state line.
Traffic blows in either city. Atlanta drives faster, we have massive gridlock. Pick one or the other.
Boston and Atlanta both have great nightlife--tie.
Both have great food, restaurants, dufferent styles but both good or great---tie
Taxes are high as is cost of living here. I can't say about Atlanta, so you decide.
Schools, if yo uhave kids, most of the schools in MA, non college are pretty good. Colleges, well we have some of the best.
I love Atalanta, the 6-8 times I've been there, I had a blast........I think

some great bars
Around Boston, again I'm north of the city, I can be on some great uncongested mountain, twisty roads in 30-45 minutes.
Mount Washington is about an hour north of me.
I can be IN the Atlantic ocean in 35 minutes.
So depending on the pay scale compensating for the higher
cost of living, your call. Me I'll go with Boston.
Oh an insurance in MA is regulated by the state, so we are one of, if not the highest cost for car/auto insurance.
