I think that flops like QJx or QTx are pretty good for us if the villain's range is polarised, and pretty meh if it's unpolarised. Sometimes we flop 78T two tone and have to c/f but whatever.
Something I was trying to make apparent is that the logic that could make those boards decent is the same logic being used to justify the call pre. I think it's completely safe to say someone is more likely to 4b blockers here and a value hand at this point in their encounter than say 76s or 83o. Either way, if you really want to argue both sides then we don't have a clue as to what his range is and WILL ABSOLUTELY MAKE MISTAKES POST. So lets just assume value hands and blockers, because that's far more likely and avoids an unneeded discussion.
We're still likely to have 24% or so equity vs a bunch of hands that's made a pair (AJ/AQ/KJ etc) though even if he's unpolarised and sometimes we're up against other gutters and straight draws that we have crushed. If he has like 98s or K2s then we can say hooray and either call down or just ship over cbet, depending on how likely we think he's bluffing on future streets.
Once again, we can't argue both sides. If we do, we're already admitting it's bad because we don't know how to play either board. Based on your example though, in the case of a depolarized range we're getting it in with 24% equity or taking down dead money on the flop. Or we can take down dead money pre and get it in with 50% equity? Plus, we ABSOLUTELY HAVE TO check fold some boards. It's not close.
