Superman should be praying to The One Above All or at the very least Galactus so that Nimrod doesn't show up and obliterate him. 1% of Nimrods physical strength is enough to wipe Superman out, ripping his limbs clean off his body with almost no effort. Nimrod solo'ed Juggernaut for christ sake.
If Kal played the sissy card and flew away, then the Sentinals would adapt and become teleporters or invoke some flight capabilities. They didn't need any of that to take out the final group of mutants, they were more than capable of killing everyone on foot and without any means of propulsion or teleportation. Their ground game was more than enough, just a handful of them took out some very powerful mutants.
Sentinals take this with minor losses. I say Kal takes out maybe 10 out of 100 before they all adapt.
