Both are cock heads but would rather see Conor win as it would be good for the UFC/MMA all together but honestly
Mayweather is one of if not the best boxer so I would be happy to see Conor last all rounds with him. I can see reasons Conor might win like Mayweather's age as well as retired and underestimating his opponent but I would still place it all on the fucktard Mayweather haha
