Whoever negrepped me (oh no, I'm completely distraught), I chose football and rugby because 1) I like both games and 2) they are similar.

Personally, I think Rugby is much better in many ways. There's more contact, it's a much more flowing game and I find it more physically demanding. I also dislike the spectacle of professional football. I think there is too much pre-game and half time messing, which has made it less of a sport and more of a circus.
