Gorr...although I hate this character, he just looks perverse to me for some reason.
But King Thor was able to end Desak (in Destroyer armor nonetheless) with a single hammer throw. I don't think Gorr would have gone down like that under similar circumstance. Plus he had demonstrated a wider use of power and tactics than Desak had that I can recall
Probably Gorr. Desak seemed a bit dependent on the fact that he was immune to divine power. I imagine Gorr would skewer him, without a ton of difficulty.

At its peak with all the godblood it had access to over the millenia, the Necrosword > Odinpower, I'd have to say. And Desak's power was nothing to the Odinpower in the end.
