Goku > Superman.

Not least of all because Goku has only had one incarnation that retconned his abilities (SSJ4 Vs. SSJ God) and only one shitty western-film-industry live-action movie. Superman is constantly fluctuating between 'Sneezes that Destroy Galaxies', 'Lives in the Sun because Kryptonian' and 'Kryptonite? What's Kryptonite? I'm super scared of different atmospheres you guise, but check my sick eye lazors.'

EDIT: No matter what anyone says, Kung-Fu Hustle is the unofficial live-action Dragonball movie following the exploits a young Master Mutaito.
