The Usenet Oracle has pondered your question deeply.
Your question was:

> In the 70s there were several crossover comics between Marvel and DC.
> In a typical weenie move, they decided to pit Superman against Spiderman
> in one.  In an even stranger move (it's beyond weenie it's just plain
> weird), Batman was sent up against the Hulk in the other.  Instead of
> the above, most comics readers would have rather seen Superman sent up
> against the Hulk.  Who would have won?

And in response, thus spake the Usenet Oracle:

}  Oh, puh-leeze! I have knowledge spanning the infinite breath of the
}  cosmos itself! I know all! I see all! I know all the great mysteries
}  of the universe! I know what quasars are! I know who built the Easter
}  Island statues! I COMPLETELY UNDERSTAND WOMEN!!!
}  
}  AND YOU HAVE THE UTTER NERVE TO ASK ME WHO WOULD WIN A FIGHT BETWEEN
}  SUPERMAN AND THE HULK! WHY, I OUGHTTA--
}  
}  Wait a minute. I don't actually have to answer the question myself,
}  now do I? I'll just create two simulations and pit them against each
}  other! They'll settle the situation while I go ponder more important
}  subjects!
