There are so many good arguments here in favor of 3betting the flop.

Here are some random ones:

BvB, loose/aggro villain, we only rep JT (fo value), we're deep, we have the nuts, we're not a nit (i think), its a fairly drawy board, its unlikely he keeps bluffing on many turns (imo), a lot of turns will instead hurt us...

edit: in vacation right now sry for the simplistic "analysis"
