In the manga, Goku steadily increases his power over time, while Superman is powerful almost from the get go. Superman is created to be basically a god, able to do feats that are just too unbelievable. In this kind of match, Goku was the underdog, but in a way he had never been before.
Are there scenarios where Goku could win? Well sure, several of you guys pointed out many ways in which Goku would have won. But the guys at Death Match looked, not only at their power and abilities, but also at their personalities and traits. And for all accounts, the Goku I saw in the fight was the Goku I know. From wanting a fair fight, even to the point of destroying the only weakness of his enemy, to using the KameHameHa to throw Supes in the Sun, and then realizing too late how the star affects Superman, this was Goku, no question about it.
As for the Man of Steel, I learned stuff about him I never knew. Simply put, the guy is off the charts. As soon as they finished presenting Superman before the fight, I knew he was going to win. That punch alone was hax to the max. No wonder people say Superman is too damn powerful to make him a relatable character. Although Supes is still my favorite comic character ....not that I read much comics haha.
At the end of the day, Toriyama put limits to Goku, to show effort, perseverance and a hard fought win, the basics of a shonen hero. While the different writers for Superman just give him the strength the story needs him to have. They need to move a planet to make the story spectacular? well, lets have Big Blue dip in the sun for a bit, and then we can say he's able to do it, because why the hell not? So yeah, who wins the fight between one who time and time again goes beyond his limits, to one who simply doesn't have one at all? We just got the answer.
Superman won, in an awesome fight, and I believed it.
But you know, this made me think of something. Battle of Gods. Yep, the movie, in which Goku seems to be out-classed by a god of destruction. This new enemy could very well be the closest thing to Superman there has existed in Dragon Ball, so let's see how Goku deals with him, and then come back here with that new piece of info, shall we?
