Well, everyone is pretty well versed on what Hulk's powers are, so here's a page with some specific numbers for Superman's power. Link
Okay. Yes, hulk was able to hold up a mountain, but this was only because he got a MASSIVe adrenaline rush from the fear of seeing a mountain falling towards him. Does anyone honestly think he'd see SUPERMAN and be even remotely terrified?
I'll be nice and say Savage Hulk starts out at 200 tons. Well, Superman is in the neighborhood of 100 THOUSAND tons starting out. Hulk can withstand 4000+ degrees of heat? Well, Superman's heatvision does nearly triple that right off the bat. And, since it's energy, it travels at the speed of light. Hulk has no choice but to "stand around" for the split second it takes for those beams to start cutting into him. Despite what many people think, heatvision isn't visible, artists draw it for art's sake for the same reason they draw bubbly light whenever Professor X or Jean Grey uses a psychic power. So Hulk isn't going to see Supes eyes glowing and be warned.
You people do not give Superman's super speed the credit it deserves. It doesn't just mean he runs fast, it means the when he's using this power he thinks and reacts faster than anyone but the Flash!! In the time it would take Hulk to throw a punch, miss, and pull his arm back, Superman could dart inside his reach, land twenty kidney shots, and be out of arm's reach again. It doesn't matter if Hulk gets up to mountain-lifting levels if his opponent is too fast to hit! Look at Spider-Man, he wins against stronger opponents for the same reason: he reacts too damn fast!
Sorry everyone, but if the writers were being true to both characters, Hulk is going down.
