Ultimator vs Hunger

I haven't read anything with Ultimator in it, but from what I understand it consumes realities. Is this being even greater than the reality eater known as Hunger?

hunger eats realities(universes )
ultimator eats whole dimensions, i assume its the hole 3d multiverse.
i also think there might be a 4d multiverse or 5d multiverse, or are the other dimension just pocket dimesnions within the 3d universe?

Ultimator the 10th being.
