Jyggalag was far from his height of power when you defeat him in the Shivering Isles. His alter ego literally spent the last six main quests instructing you to do every possible thing to undermine him, and you've gained throughout this process control of the realm itself, which is what I really think is the defining point: he's fighting you on what is now your turf, where normally he's attacking a godless, mortal-infested realm he now has to fight someone who owns the place. But that power doesn't extend to you outside the Isles. And you don't destroy him, you disrupt a tiny avatar of his power and he floats there afterward as a head to tell you that not only is he not damaged, you've restored him to his original sane state and helped him immeasurably. You basically slapped a whole load of sense into an insane Daedric Prince. Even after gaining control, you don't have godlike powers, even in the realm itself, outside of changing the weather.

Also, though this probably doesn't mean much, I definitely feel more powerful playing Skyrim than Oblivion, because as a mage in Skyrim I can bring the pain to my enemies instead of running backwards desperately chucking slowpoke fireballs at them hoping they die before they manage to land another hit.

I think overall I find the Dragonborn to be more powerful because his power seems to exist regardless of what the princes/gods think, as seen when he destroys Alduin in a realm mortals can only enter after dying, and then gleefully walks out. Your power in the Shivering Isles as the Hero of Kvatch exists only because Sheogorath lets you have his.
