616 cap. Panther will have his hands full with Midnighter. Guy has been a beast lately. He'll soon fight a being with Superman's powers and a computer brain like himself.
The way I see it though is Midnighter's usually moat brought up device is "Doors" That's been commonly shown to be something that needs to have someone pushed into.
I think Midnighter vs Black Panther would probably be one of the biggest issues here and a pretty awesome fight.
In terms of who've they fought we can't say much on the Midnighter fighting the powerhouse yet because it hasn't happened, but under Hickman's pen Panther has given a beating to Namor who under the same writer survived blows from Thanos so that's not to being taken to likely if we're going for what a writer was shown for characters capabilities of recent. Panther also beat Black Dwarf one of Thanos's soldiers but the fight was mainly off panel so take that as you will.
I think what Midnighter will have problems with is Panther's speed and the fact he can cloak which is dangerous considering he has gear like vibranium knives that can cut through Warmachines.
He also has teleportation tech that's pretty deadly.
