Let's get down to it, a 1.6x AP Advantage for Blue Marvel, as he contended with Sentry, nothing'll help there other than his punches pack a bit more of a hit for the Man of Steel. However, Superman does have far higher Lifting Strength, so he could pretty easily restrain Blue Marvel if this was an all out slugging match.
Speed should be equalized, unless Superman would blitz very, very hard.
Superman basically resists all of his hax except Antimatter Manipulation, but as far as I know, Blue Marvel only uses that by absorbing Antimatter into his body to give himself a boost, so I don't know if that'll be much here.
I'd probably have to go with Superman, honestly. He seems to be far more skilled, and basically all of his powers could help him get a better beat down on Blue Marvel. Besides he can quickly close, or even surpass the AP Gap with a Sundip, securing his title as victor even more.
But, still, speed needs to be equalized, or else blitz, if it gets eequalized, Superman gets my vote.
So Post-Crisis Superman > Blue Marvel > King Hyperion = Post-Crisis Superman? How does this make any sense? How did Post-Crisis Superman beat Blue Marvel yet he couldn't beat King Hyperion even though King Hyperion lost to Blue Marvel in the comics?
