I think the big club competitions in each sport (premier league and champions league, premiership and Heineken Cup, county championship and T20 cup) are all quite similar in their excitement levels. They're all pretty entertaining to watch as a neutral, and exciting to follow as a supporter.
However in international sport, rugby and cricket kick football's ass. International football is really boring and defensive compared to the gung-ho premiership style, whereas international cricket and rugby go up a level of excitement and intensity as well as quality.
How can anyone who appreciates sport even just a little bit try to tell me that Newlands Test Match wasn't an incredible sporting spectacle?
