GEB one-shots. TOBA barely did anything noteworthy, aside from sending waves of monsters to attack Hulk.

TOBA loses, with ease.
Even if the stupid retcon demoted Spectre to only sending a "fraction" of his aspect (As if a being on Spectres level couldn't be at full power in two places at once, since he doesn't need to operate in our concept of time), the GEB has far superior feats.
