I'd always fold pf but if I hadn't, I'd donk the flop. Any reasonable bet puts UTG+1 to a stack decision and if he's willing to ship it in then on that flop, he wasn't bet/folding the flop anyway and generally not letting you see a free turn or in any other way presenting a way of taking the pot away.

As for the other guy, if UTG folds and he calls, that's no bad thing this deep even OOP for a cash game player? He'll be a bag of timing and bet size tells and will give you two cards more way more than most here, if I've got a handle on the type.

Obviously, if there's no flop you'd ever donk, then don't but I think our best chance of turning a profit, once you're there, is on the flop.
