Who wins?

Not sure on all of Lex's showings and feats in his warsuit, and I don't have audio on my computer so I can't watch the videos, but I thought I'd throw a few things I know about for Lex.

He gave a weakened Superman a decent fight, beat the shit out of Supergirl(although Kryptonite was involved) including apparently no selling her kick to the face and making a force shield(not covered all over him, closer to a GL construct) to block her heat vision, hurt Dark Kara a few times(once with a punch, another with an electric shock, the third was with a Kryptonite shank so not relevant to Iron man) but she fought a lot smarter than Supergirl, and he one-shot killed three or four OMACs with his suit's energy blast.
