Ali holds it. He's the best heavyweight fighter ever.
Joe Louis has a chance as well though.
Depends the order of fights I guess, if Joe Louis wins it from Ali, then Tyson has a shot against Louis. If Tyson gets it then Liston could come along and beat him.
All told though I think Ali does it, if all the fighters fought each other 3 times. Ali would come out with the best record in my opinion.
