American football ( Gridiron is what it used to be called in Australia) is a nice strategic game much like cricket IMHO. Learned to love it when I lived in the USA
"Football" the so called world game as the European dominated federations like to call it ( Soccer in Australian terms, Association football in UK terms strictly speaking I believe) is an even slower more boring strategic game without the strength and impact of American football or most other "footballs" . The play acting dives for a penalty are comical though.
League Rugby in Australia, and some other countries ( not sure what its called elsewhere) is similar to American football but a little quicker with less stoppages and without the set plays
Rugby in Australia ( Union in UK terms I believe) is a better game again provided it does not get dragged down in scrums too much. The All Blacks are the premier sporting team in the world based on their mastery of this game over many years against all opposition ( they say is the game played in heaven)
But Australian Rules football is truly the premier game and the only true football. It is the earliest codified football in the world even before UK association football. But most people in the world don't understand it. Just like they don't understand what Lotus is all about for which I am forever grateful.
See there was some Lotus content
cheers
