I know TOAA is the creator of the Marvel Multiverse, I'm just not sure it automatically equals Omnipotence (many high-end reality warpers created their own uni/multiverse while being far from Omnipotent).

Well, as far as we can tell Omnipotence is a purely fictional thing, so it can only be had by characters, which are by nature mere tools in the writer's hands. So practically speaking, storytellers are stronger than Omnipotents.
