Michael Myers from Halloween would have the precision and stalking abilities to take down Jason Voorhees and claim victory. Pazuzu from The Exorcist would outmatch Jason Voorhees with supernatural survival skills, as Jason's strength and ingenuity would be useless in a physical fight.
Its extremely difficult to kill Jason but he can be stopped or killed. In Final Chapter we saw Tommy Jarvis finally kill Jason with multiple machete blows.
