I'd check, can't think of enough hands he'll call with that you beat. Sure J weaker kicker or 8 might pay you a bit, but more likely he has flush or str, sometimes a boat waiting to raise. Plus I want to see his cards if he is way off here to judge the variety of donk for future hands.

BTW I'd also play the flop much harder. Either pot bet or lay for a max chk-raise
