Sin is just as invincible, so it would end in a stalemate, not in Sin's death. You also seem to be forgetting about Giga Gravitron; the fact that it results in a Game Over even if you have an Aeon out means it's not just a flashy attack like Particle Beam, Big Bang, or Supernova. Plus the only reason you could even have time to defeat him before he uses it is due to Jecht's influence and the Hymn.
Particle Beam is an instant-KO move, though, just like Giga Gravitron, unless Cloud of Darkness is weakened. So when we put CoD versus Sin, it's one instant-KO attack versus the other, with the difference that Sin has to charge it, CoD can use it at any moment. I know Sin had that pretty strong shield thing around him during that operation in the story, making him almost invincible, but it's the same really with CoD. She could be Particle Beaming the Hell out of him until his shield is gone, while Sin might use Giga Gravitron once, not harming her since he can't unless he... well, you know by now. And once Sin's shield drops, it's game over for him. Or they both could continue attacking endlessly. Both not being able to harm each other with their Hero-killing attacks.

And if Sin really starts to get annoying, CoD would just return the world to the Void where nothing exists. How she would do that I have no idea, but her sole purpose is to do that, so I guess she can do it. And by returning all to nothing => Bye, bye, Sin. Same way NeoExDeath, True Ultimecia and Necron could kill Sin.
