Hulk also has a limitless power source, but he also has no limits to how much of that he can cope with... his experience and mentality should give him the decisive edge.

How can you say that the Hulk has a limitless power source when it was clearly exhausted during that fight with The Sentry?

To use a non WWH example, Silver Surfer drained all the energy out of the Savage Hulk. And despite the hyperbole by Marvel, the savage Hulk is the strongest version of the character.
