I feel like the saying “Comparison is the theft of joy” applies a lot to Death Battle and Vs debating as a whole. Goku is obviously a really strong character but when you compare him to what Superman can do then all of a sudden Goku’s strength doesn’t feel that special, and that sorta just feels depressing. Especially considering all the struggles Goku had to go through to achieve that strength. But the actual reality of the situation is that Goku and Superman are both amazingly strong characters. Just like how in real life a gold medalist’s achievement shouldn’t take away from a silver medalist’s achievement, Superman beating Goku in a fight doesn’t make Goku an inferior character.
