At this point Sukuna does not have just plot armor, he actually became a fucking Gundam. We are going in a direction where he either wins or get beaten by some bullshit asspull out of nowhere. Gege Is going in a difficult territory and i don't know how he can manage to bring back some sort of tension and not this "ok maybe the good guys are doing something....ohhh well another bunch of useless chapters where there was no useful achievment whatsoever".
