Jason's an awesome stalker; he doesn't have a high-tech alien camouflage unit to rely upon, yet he manages to appear behind you; seemingly out of nowhere. So it's arguable who's the better stalker. The guy that does it with tech, or the guy that does it with nothing.
Strength, again, Predator from the first film didn't have all that much here. Jason [1-7] does. In part IV, he crushed a man's skull with his bare hands.
Speed, when have the Predators, any of them, shown "great figthing speed"? They can run away very fast, sure. Even then, Jason has that ability to get in front of people, even thoguh they're running away from him at a much faster pace.
Damage-soak, Jason has this hands down, by a mile. Plus that healing factor.
If we're going with the best Predator, ie Wolf from AVP:Requim, then we should include all of Jason's movies, barring Uber-Jason, as that would be a stomp. Even then, Jason still wins in a H2H fight, as he has even greater strength feats and massive damage-soak to draw from.
