I think betting out is probably marginally profitable. You have enough of an equity edge to bet and hope for a couple callers if all your outs are good. The coldcallers in the hand are your only worry, you have to discount your outs (and equity) a bit based on a possibility there is a bigger flush or straight draw out there. Without the coldcallers, this is a bet every time. With them, I still think it is best to bet out, but I don't see a huge issue in taking the free card.
