Goku VS Superman is so fucking retarded to me because when it comes down to it, you have to essentially cherry pick many of Superman's feats, some of his best ones are ones where he's amped up like his fight with Imperiex or the recent one where he smashes a God-like entity. You've got times when writers are writing an unamped Superman as a god but that's only a few.
Like, Goku's feats are consistent.There are no "versions" of Goku like Superman, no worrying about what different writers think Goku's power is because in the end, Akira Toriyama is the one writing him or atleast supervising the stories.
So yeah, I don't give a fuck. Superman'll win because he has a literal laundry list of feats but in reality if you pulled up a recent Superman arc and said that THIS Superman can beat Goku, I can guarantee that you're wrong. But if you pulled up, say, the Final Crisis comic where the Thought Robot washes the Dark Monitor, then yeah, Goku loses.
See what I mean? Shit's fucking complicated. All we know for sure about Superman is that he's strong enough to destroy a planet, durable enough to endure a supernova, and faster than the speed of light at best.
