Superman can't actually fly. That's a misconception that was picked up in the later days of the cartoons. He can only jump really, really high and far. (leap tall buildings in a single bound)
His pop would be amazing, and he'd be invincible. So I guess that's an advantage.
Jesus can walk on water, so he could do some cool puddle stuff.
Homer seems to have a lot of luck, so I'd assume he'd be able to pull off a lot without knowing it. Plus, he's one tough bastard, so he could take his spills.
However, none of these three people have any experience, so they'd just be hucking. And even with his godlike pop, superman would just overair all the jumps and his skis wouldn't hold.
So I say that Vinnie would win.
Drunk, hooked on crack, lying in the gutter curled around my skis in the fetal position wearing nothing but the head of a chicken suit.
Damn I hate fall.
