bad comparison my friend. The sports are just about two different things altogether. Appearance vs. Strength. Powerlifters are stronger without a doubt but world record squats is not what bodybuilding is all about now is it?
If its appearance vs strength than one definitely seems more a sport than they other. Hey, I love bbing, but its more of a lifestyle. Powerlifters like football players, basketball players, and boxers have to back it up, and they deserve credit for that.
