okay it would be close mainly because of Parkers intellect and supermans arogence. spider man is very strong, agile, and fast with the cosmic power he can stand up to superman. The deciding factor is superman has a weakness a rock(Krytonite).
I think you've been provided a few reasons for Superman. Superman is faster, a lot stronger and more durable. Uni Spidey's one chance would be to produce K-Nite with his energy manip, but that's a big if considering he'd have to know how and why K-Nite affects Superman to begin with to produce the radiation.
So Superman more than likely takes it.

It's in the respect thread somewhere. It's an issue where Superman casually tosses a mountain big enough to crush metropolis into the sun from Earth. The pic posted in this thread is from a damaged/weakened Eradicator.
As for this thread...Superman wins. See pissed off Supes vs Blackrock.
