I go to Brooklyn about 4-5 times a year, may start to more for work / honestly just considering just moving to New York next year, so I’ve done the trek quite a bit (also through Boston when I lived there too, deff easier from Boston even if it’s technically longer to get to from there)

Flying is the easiest way through ORH (though the carbon footprint!!!!!). And getting out of JFK takes far longer than the flight, I’m gonna try Delta to LaGuardia next time.

The Greyhound or Peter Pan from Union Station is honestly fine depending on the driver, though I avoid that method in the winter months if there might be snow.

Or if you have friends in Boston like I do (take commuter rail to get into Boston) I’ll stay over with them and then take an early morning Acela Amtrak train. I guess you could also drive down to Providence or New Haven to catch the Amtrak train, but that somehow in my mind seems like more work.
