One of my friends is a comic supergeek and he always argued Hulk was stronger than Superman. His logic was based on Guardian and some other character from the marvel alternate universe. Basically, he said the stuff lifted (buildings, jumbo jets) would crush under their own weight if some aspect of Superman's strength weren't levitation.
I haven't read comics in forever but guess it would come down to what the writers wanted without any logic necessary. If it were a matter of pure strength I'd go with the Hulk unless Superman's intent was to kill.
that is true, part of supermans strength is some sort of levitation power - superman has said this himself, but its never been explained properly as far as i know.
Bigkev is melting bigtime here thats countless posts in this thread where he is melting into oblivian. quite funny really, especially as he clearly has no clue at all about comics.
condor as we have now agreed the hulk is the strongest one there is

how about superman vs thanos and superman vs thor? who do you think would win those and why?
