But still, what if we did say that Danny could scale to universal levels of power? Surely, that is far beyond anything that happens in Yu Yu Hakusho, right? Well, not exactly. Believe it or not, Yusuke has the means to match such a power level. According to Koenma, the Spirit World has no means of fighting an S-Class demon. In the official dub, he even specifies that his father King Enma cannot do anything to fight them, and that is notable, because King Enma was once able to destroy the entire Netherworld, which is its own entire dimension. In Yu Yu Hakusho, these realms are referred to as parallel planes of existence to the main universe, similar to the faces of a die, and the Netherworld is the counterside of the Demon World where they balance each other. If the Netherworld is thus similar in scale to the other dimensions, then that means that King Enma was able to destroy an entire universe. Even if you argued the Ghost Zone is infinite because of Skulker's statement, Koenma said the same thing about the Demon World, which the Netherworld would be comparable to. Because of the aforementioned gaps in power, Yusuke would still be significantly stronger than Danny, no matter what end you use. Yusuke takes the edge in raw power.
