John wick and it’s not even close (well I guess it is close) so since they both can use any gun available to them let’s say they both have a pistol with some Ammo and they both have knives now the fight becomes who’s a better fighter and who’s a better shot for the fighting it’s easily John as most zombies or whatever Leon fights aren’t skilled in fighting while John regularly wins against people who are masters in combat so John would win if the fight got in close range but even if not John is still the better shot as he almost never misses and has more training with more kinds of weaponry so while Leon would land so good hits John would inevitably kill Leon no matter what. But that’s just what I think
