I dont know much about Silver Surfer, but its said that he can find the weakest point of anything, then touch it and it is destroyed. So I'll have to go with SS.
this is what wizard said about a surfer vs superman fight:
"While Supes might land a couple of blows as the Surfer is trying to talk to him, our bald buddy Norrin could either hammer Supes into submission with the power cosmic or suck all the solar energy out of him with his energy manipulation powers. "
Before you close this Paola let me throw in a quick jab...
Did any of you see the comic where Gladiator(Superman's clone and equal) went blow for blow with Surfer and no side gained the upper hand?
The Comic went like this(to a tee):
Gladiator and the Shiar forces were journeying through space, suddenly they came across a giant living planet(Ego), Gladiator along with the Shiar forces proceeding in attempting to "dismantle' the living planet as they deemed him "a threat" to space.Surfer comes out of nowhere and battles Gladiator in a blow for blow "even" battle, Surfer's plea is that Ego is a "living being" and deserves to live thus they fight it out in a blow for blow EVEN battle, no circumstances, no holding back, both fought for the win.Surfer is about to give the battle up as Glad is beginning to gain the upper hand.Ego "realizing" that Surfer was on his side donated some of his power to Surfer in attempts of ridden himself of Gladiator(his threat)..Surfer "still" didn't topple Gladiator, the fight ended in a stalemate as Glad decided that Surfer's way of piece was the "right" way..
Surfer used no power draining whatsoeva, it's assumed that it wouldn't work because or else he would have saved himself alot of trouble against Gladiator..
