More like worlds would be utterly destroyed, considering all these warriors have destroyed worlds before...
Eldrad. He's the biggest, scheeming dick in the known universe, on par with Tzeentch and the Deciever in dickishness. Marneus is a smurf, Abaddon is an armless failure, and Gazghkull is an ork. Nuff' said.
Calgar: To busy being Mary Sue. Abbaddon: 13 failed crusades. Need I say more? Eldrad: Wouldn't even show up to the battle because he's a d***. Ghazkull: Big, green, mean. Literally a prophet to Gork and Mork (or Mork and Gork). On a sidenote, Eldrad probably planned that Ghazkull would win. Because he's a you-know-what.
Eldrad is a pussy, Marneus is an UltraGay, Abaddon has so much power but he's a complete retard, and Gazghkull can't even kill Yarrick... So I guess it'll be an endless fight...
This discussion can lasts forever, but if they would appear as in-game caracters (non-playable, obvious), we'll finally discover a truth.
On the Table probably Abaddon, but Fluffwise I would go with Ghazghkull, as he Abaddon would Fail... again
