I didn't think "the floor exercise" was any more manly.
Almost every "sport" has an easily defined winner/loser. You scored more points or crossed the line first. The ones who have judges are always a little sketchy. Even MMA/boxing have their problems when they go to "the judge's cards". And that's after two dudes beat the crap out of one another.
In truth, "best" anything is a pretty much an argument that can't be proven beyond question. Best NFL team in the last 10 years? I think most would say the Patriots. But I'm pretty sure the Colts won more games.
