They're both strong af. Goku has UI and Superman is just Superman. And I always wondered why people struggled to beat them if they can match/rival them in some way. Even though they may be indestructible, or strong and fast as hell, that doesn't stop them from feeling things.
So if someone were to throw dust in their eyes they wouldn't be physically hurt by that but it'd be a setback. What I'm saying is even if someone cant physically match them, if they have abilities that could hinder them(a setback) even if it doesn't hurt them, couldn't they still win? Like Sasuke did to Danzo with that very subtle genjutsu of making think he had an extra eye. People like Sasuke could beat them if he just manages to force them to do something without brute force. Cause that's all they are really. Tanks.
I don't watch db that much or read Superman comics so mb if this is an obvious question to y'all. I'm aware Goku basically benchpressed a black hole and Superman flies at like the speed of whatever's a million times faster than light, but I always thought little subtle tricks would deceive them in a fight and they could be easily beaten that way. Especially since Goku isnt smart so it shouldn't be hard.
