OWAW Superman, who oneshotted Trans+ Probes was infused with the Loeb Force. Sans FC and OWAW I would say that DCnU Superman is on par with pre-Flashpoint Superman, Brainiac Ship, benchpressing Earth, ripping DD (a HH-Trans) while weakened, traveling from the End of the Universe to Earth within 60 Days, surviving multiple Black Holes etc. That's a bunch of uber feats within a very short time compared to pre-Flashpoint Superman.
KC Superman however, though lacking the feats is an older and more powerful version, he should be, by any means above DCnU Superman AND pre-Flashpoint Superman.
