I see.

Not yet, my biggest issue is about comparing their combat skill. I know both characters, but Kraven not too well.
Goku might succeed in getting closer, thanks to acrobatics, his staff or else, he also already knows the Kamehameha, in case he wants to counter projectiles with projectiles.
In close combat I think Goku has the formal advantage with his martial arts and the fact he can give a hard time to actual masters end experts like Roshi.
Kraven though has more experience and is no slouch himself, he is also clever and has those darts in his wrist that would be troublesome for Goku.
If they clash with weapons, I think the power poll is the better one, given its size manipulation and durability, which makes it far more resistant than spears, axes and knives, assuming they are not supernatural, although their should be unnaturaly strong as they can harm Spider-Man.
Ironically, Goku's monkey-like style he pulls off at times woulnd't be a problem for Kraven, as he's used to fighting that kind of animal, and wouldn't be disoriented as other DB characters were when facing that style.
