All very viable points.
If it’s the original Jason of Parts 2,3,4 then I estimate John Wick has a 65-70% chance of winning due to it being possible for Jason to die and but he is still built like a brick-shithouse
If it’s Undead Jason then I estimate Jason has a 75-80% chance of winning and if John Wick wins then he will simply subdue Jason with a smart plan of some description.
If it’s Über Jason then John has no chance with the modern eras weaponry.
If it’s Reboot Jason then it is actually closer than you think, because we don’t know the full extent of this Jason’s powers and endurance but what we do know, is that he is incredibly smart and able to set up traps, so I believe that if this fight were to happen at Crystal Lake then Reboot Jason would have a 55-70% chance of winning if he got a good trap set up.
I’ll be honest though, I just can’t see Jason killing John Wick. I feel like John will be able to subdue him and barely escape out alive but technically clench the win especially if this were a movie Wick would have plot armour aswell.
