Harder Hitter: Plastics Margarito or Pacman?

Pacquiao has explosive punching power, the kind of power that will knock you clean out and you wake up in hospital bed. Margarito has heavy handed power, punches that have a lot of weight behind them and slowly break you down. Id fight Marg and just run away from him the whole fight, hes slower then Pacman

For one million dollars they can do one round each and bring in one more fighter so every fighter is fresh for the whole round
