if superman can be killed by doomsday.
hulk would kill him too, and still be standing.
are you now denying that the hulk has strength limits? his strength has no limit - that hulk was an older hulk version, brought on by experiments and different techniques to try to limit/control the hulk. there is no more savage banner, only hulk !
in wwh he almost broken the world apart. he beat every marvel character, except thor who was hiding. 
Im old school... my friend...
i go by what the guy who created the character says...
and thor was brought in to be a match for hulk strengh wise.. stan lee the man saidd so himself and thats without counting the hammer....
these new writers.. are all twisting thisng.. for sales.. sales sales....
world war hulk was crap.. badly drawn.....
for instance we know when black bolt speaks it can destroys worlds..
he whispered on hulk and hulk lives so hulk is tougher than a planet...
ha ha u have to remember comics are written from writers imaginations.. so i stick with the basic fundamental rules layed down by the creater
did u know bat man one beat the hulk
that is an example or a writer fully employing his imagination rather than going by the fundamentals laid down by the creater.
