I see WS Caitlin on equal footing with She-Hulk, myself. Not sure where I would put DCnU Caitlin. She seems pretty durable and strong from Superboy's confrontation.
I meant the "other" WS one. Gen 13 actually did a full on reboot after the Worldstorm debacle. New Caitlin was still technically Wildstorm, but seemed pretty toned down.
Then again, I quit reading around the time Gail Simone left the book. Maybe she got some better feats down the road.
Old school Caitlin wins though. Excluding maybe Bendisforce Cage.
Cage survived being in the middle of a nuke, found a ship to fly out of New York, made it to the Savage Land before crashing, and then crawled miles until he met Ka-Zar. He was near death and close to dying, but the fact he survived all of that is ludicrous.
Conversely, She-Hulk gets shot in the head by an Ultron drone and is presumably dead.
It's not what I was expecting from Bendis. It's basically a bunch of exposition with some random feats thrown in there for shock value. As of now, I'd say his Heroic Age arc that foreshadowed Age of Ultron is better. Which is a shame because the dude can write a good book.
