3b pot with nfd

It's incredibly frustrating indeed, but I do not expect to see a bluff here, and honestly I see reasons to call and reasons to shove.

Call: we have probably no FE, Tx does poorly against hero's shoving range but Tx does not fold. We can donk if we hit and still get villain's stack. Pot odds are good (20% equity) so we can go for this play knowing that we can outplay villain and have the discipline to x/f a non spade or 9-8-7-6 (we need to x/c 5 and below and J and above given pot odds)

Shove: we're OOP, it's certainly OK with all the dead money, we have 50% vs his Tx, we're sure it's profitable. Occasionally we may get 55-44 type of hands to fold. It's better for the redline

Basically they're both profitable, but I am not sure which one is the most profitable. I guess call IP is fine.

"Really poorly" is probably too harsh, but indeed it does feel like hero is undergoing the hand and forced to play passively/hit or fold on the turn in a huge pot and it feels disgusting. It's a close fold without rake so with rake it's definitely a x/f turn as played.
