If we're discussing pure strength vs strength then I think it's in Jugz's favor.
There was a scan of an article by one of Marvel's guys basically saying Jugz can increase his strength by drawing on more power from his Patron when he needs too. I think it was in the Respect Juggernaut thread.
That + Invulnerability wins it IMHO. He don't need to eat, breathe, or sleep. He'll never get tired. Imagine if he takes the fight underground or underwater where oxygen is scarce. Then what's the Hulk going to do? Make himself so angry he don't need to breathe? 🙄
Or worse, imagine they wind up actually destroying the planet they were fighting on. Now the Hulk is REALLY screwed.
