I'm pretty positive it wasn't Meteor, since that was before Jenova had control over him, which means that he wasn't on his quest for the Black Materia yet, which is better known as Meteor. He destroyed Midgar, then went into Mako Reactor Number One to take Jenova out, which is when the whole Cloud getting impaled and throwing Sephiroth scene took place, or so I believe.

I don't think that last scene with Cloud and Sephiroth is a true indication of Seph's powers though. It was like in DMC, when Mundus was a piece a pussy cake while trying to flee in the last scene. He was basically there for the final touches, and Dante was assisted by Trish to finish him off, which is basically identical to the way Cloud gets his Break Limit for no apparent reason other than intense rage. If you were dumb enough (Not you Raz, just in general playing the game) not to use Omnislash to finish the game, then they made the game so you would counter and kill him, so you couldn't possibly lose, which was the point of that last scene, that Cloud couldn't lose.

I don't really have anything to base Dracula's fighting abilities off of, other than reputation of him being the Lord of Vampires, which honestly means nothing to me, especially after seeing Blade!
