Which is the first choice? Mayweather/Pac or Cotto/Pac

I expect honest answers (May) weather you are bias when it comes to any of the three.
This is the scenario. It is a warm saturday night in Las Vegas. You have an optional ticket. Ticket A takes you to see Mayweather drill the Pacman. Ticket B takes you to see Cotto vs Pac. The biggest draw happens that night. Choose wrong and you are S.O.L. Pick your fight.
