Mr Miyagi vs Mr Han
Mr Miyagi from the 1984 Karate Kid vs Mr Han from the 2010 Karate Kid. Who wins?
First fight is in a combat arena, it's an exhibition fight, rules apply, no illegal punches, etc.
Second fight is a street fight, no rules (though both seem kinda like decent guys, so it's not a fight to the death - maybe they are just fighting over the last bottle of sake 😛 ).
