Why do you keep including SS, he can't draw energy from anything, neither can Hulk. Sentry, by statements, can. So both he and Hulk have their own infinite universe to draw power from. And if you have unlimited credit, a trust fund is pretty useless.
Surfer just shows how it is something not entirely uncommon to high heralds.
Sentry's statement can be taken as basically a loose description of what Surfer does (take energy from many many forms within the universe) but he shares that source with other beings who take even more energy from it (Galactus, his heralds, other cosmic entities).
The point being that he never truly has full access to all that energy and if he fought someone else hooked up to the same source (like Surfer) he'd have no advantage from it.
Also, without evidence (on-panel) it's a huge stretch to imagine that having access to energies from 616 = being able to channel infinite energies. Even with Hulk, we only have examples of outbursts that are, at best, on the skyfather scale (HOTM), but Sentry has been explicitly shown to have been tapped out fairly easily.
Taking it back to the analogy, you can have unlimited credit yet still have a daily limit on how much you can withdraw from the atm/bank. Hulk, it seems, has the facility to draw out as much as he wants.
