On top of that, Cosmic Spiderman was no where near the Surfer's level of power. Silver Surfer wouldn't have had trouble with the flippin Tri Sentinel that couldn't even destroy Manhattan by himself. He lost his powers because he had to expend all of it to beat the Tri Sentinel.
He lost them due to the way the powers work ... not because he had to expand it ... the power was given to him to stop the tri-sentinel .. he stopped it so powers went bye bye.
It doesn't matter what Captain Universes powers are, the fact is Cosmic Spiderman struggled with characters that Superman would kill in a fraction of a second. Cosmic Spiderman had no feats that would suggest he can survive more then an instant in this fight.
Considering cosmic spiderman is infused w/ the Uni-power he IS captain universe while he has the power so I believe that it would matter a great deal on what his powers are ... sure spiderman didn't show feats but he is infused with captain universes powers thus becomes captain universe for a time.
Next time bring feats, but I know you won't be able to, I've read every appearance of this character and he's no where near Superman's level let alone Silver Surfer. The reason why people are voting for Superman is because he's the obvious winner, Cosmic Spidey didn't do anything to suggest otherwise.
I am not sure why you wrote this as I stated I had no feats but was making a statement on how the cosmic powers work and why I think spiderman wins. This thread might as well be written Captain Universe vs superman ... but alas it can't be due to the fact that amount of power granted is based on the will and creativity of the user.
I THINK spiderman would be able to beat superman considering he is a diluted Captain Universe. With that much power I just believe, but again must point out that I can't prove, cosmic spiderman curb stomps superman because I think he would be able to tap into at least 80% of Capt. Universes powers which is enough to beat superman IMO.
