I like watching them all.
My least favorite is rugby league. I just dont think it is that skillful.
American football is just to disjointed for me. I dont like the way it takes half a day to play a 1 hour game.
I dont see much Aussie rules anymore they stopped showing it, but it was good to waste a few hours on a saturday morning.
A good a game of football(real) is a great watch, but a bad game is worse than having your teeth pulled.
A bad game of rugby is a lot better than a bad game of football. So union gets my vote
Oh and by the way.......are there any rules in Aussie rules footy
