Grey Hulk vs Solomon Grundy, with a twist

Who would win in a spelling bee?

I vote Grey Hulk, he doesn't seem as mindless as Grundy usually is.

Grey Hulk has average intelligence, unlike most of Grundy's incarnations. I say he wins this.

Grey Hulk, while not a genius, is still leagues smarter than Grundy. Make it Savage Hulk, and you got a match.
