He did it with the books which enabled him to imprison Shuma. Considering that freaking Conan himself managed to do the exact same thing, that's not exactly a feat to brag about. Especially considering that Shuma's depiction in the Conan title isn't even remotely impressive.
Odin wins. He managed to create a pocket world/dimension.
Mainstream Crom, no. He's featless, i wouldn't rank him anywhere close.
An alternate Crom did manage to overpower Mjolnir's enchantments, and this was at a time period where it mentioned that Galactus couldn't do that (in mainstream Thor comics). Still it's an alternate version so things might have been different.
Crom imprisoned Shuma-Gorath once with one-sided prep and banished him later, both times using the Iron Bound Books of Shuma-Gorath. Doesn't say anything about how an actual battle would go down between them, considering that to imprison or banish an entity that manifests outside its normal realm you don't need to be even close to its level of power.
Crom is implied to be powerful but I haven't seen anything from him of note. I'd back DC's Odin.
