I am a big fan of both characters, been a Hulk fan longer though, and I have to say, Hulk and WWH have some impressive feats of strength behind, but NON of them, NOT ONE compares to some of the things I have seen Superman do in the comics.
Superman pushed a PLANET in Our Worlds At War something Brainiac deemed as impossible, he broke Wonder Womans wrist just by squeezing it, his heat vision Melted nearly everything around it in Sacrifice when he used it on Blackrock (both of which happened in Sacrifice) and he has survived Darkseid's Omega Beams numerous times. The likes of Darkseid and Doomsday would rip Hulk apart, yet Superman has come of several fights with both.
Non of what I have seen Hulk do compares to any of this I'm sorry to say.
