He should be quite a bit above Gorr still.
All-Black the Necrosword took an ordinary street-level alien and turned it into Skyfather++ elder god level.
It then took a Old King Thor and put him quite comfortably above what was supposed to be a fed but older and possibly slightly weaker Galactus. So by my ABC logic.....
Galactus still wins. Gorr was only human level so was only amped up to maybe Odin level or slightly above. He could put up a fight, and we know that the necrosword is a universal level weapon but the being wielding it is to weak to be enough imo
