Absolon Mercator vs Superman and Green lantern (Hal)

I've just started a comic with mutant Absolon in it and he seems VERY powerful,
But I wanted to know your opinions so I put him against Superman and Hal Jordan (both before reboot) , who wins?

Mercator he is basically Molecule Man + or -

not sure he really had enough showings to gauge him fully. in theory he should handle them easily, but without the feats this will likely become a non-thread. he was very cool though. i had hopes he would be that omega who really WAS omega.
