It's different skill sets are used. It's an apples to oranges comparison. But being culturally biased I like American Football better. It's not just running, hitting, throwing. There's a strategy involved. What play to break down the defense. Which formation to stop the offense. And if you have the perfect play, there's that factor of an outstanding player that can make your plans seem worthless. Apart from athleticism, it's coaches choosing plays, players calling audibles.
