User blog comment:MrPacheco101/Burning Hearts of Courage! The World's Strongest Will Be Decided!: Superman & Goku/@comment-11009100-20120713034535

I'm going to make this short, I don't want to get into much detail.

As much as I like Goku, Superman takes this. There isn't anything I read/watched from Goku that can match Superman in terms of strength, durability/endurance, intelligence, and speed. The only thing I can give to Goku is skill and training level, but not by much.
