Think about it, if all of us can beat all other FF villians at ease, then it's no doubt that those FF villians cannot beat Sin because they are weaker than us. In fact, Sin was quite tough as a boss.
Sin was easy for me. And in-game =/= story. Like I said and others, Zeromus and Cloud of Darkness are untouchable until you use the Crystal on Zeromus or free the Warriors of the Dark for weakening Cloud of Darkness. Kuja destroyed the surface of Terra in the story but in-game he was a pretty easy boss. So well, allmost all villains can defeat Sin. Sin is not untouchable, which some villains are untill certain conditions are met. Sin cannot beat that.
And even in-game, most villains can defeat Sin, IMHO.
