So this is Spidey from "Spider-Man and the Secret Wars" #4, when he briefly held the Beyonder's power?
Here are the pertinent scans of *this* Spidey for anyone interested:

Aside from beating Galactus and Owen, this was obviously Beyonder-Spidey's best 'feat':

...But when you take the context of the entire story into consideration, Spidey(and even Doom) momentarily "remaking all creation" almost seemed like it happened as an inadvertent side effect of holding the Beyonder's power. He was never really in 'control' of it, per se... There was just a rather large 'meta' aspect to this part of the story, imo. /shrug
That said, I would go with EJ here. His power was obviously MUCH more defined, and ALL of his feats were accomplished with obvious intent on his part(IOW, Joker actually could control Mxy's powers on a creation-wide scale)... Interesting battle either way, though.
