In the comics, Hulk waged war on the X-men and eventually fought Juggernaut. Hulk was beating him. ... When this happened the fight became far closer and eventually, Hulk defeated him with some clever strategy. In reality, Juggernaut is virtually unstoppable without magic, but the Hulk is stronger than Juggernaut.

Who is stronger Hulk or Professor Hulk?

I believe in Professor Hulk form he is weaker than Hulk, and can't even get stronger from being angrier. If he was able to increase his power to higher Hulk levels, then we would've seen that happen in the most important battle of the universe. He's still very, very strong, just not Hulk strong.

Has anyone defeated Juggernaut?

The only character to have stopped Juggernaut while he was in motion as an act of pure physical strength was the Hulk while he was War, a horseman of Apocalypse and empowered with Celestial technology. When Marko gains complete access to the Gem's powers during the Trion saga, it increases his power a thousandfold.
