1:58 That was in terrible taste.
Evil, dont care
lets be honest. both of these guys are basically invincible. also, they are cross cultural couterparts to each other. Not to mention both vary in strength tremendously. Remember when the scouter said his power level was over 9000? how much do you suppose it is now? even toriyama admitted the scouter was a stupid idea, because the numbers would be absurdly high by now.
Meanwhile, superman has been through more than 60 years of revisions, including to his overall strength level. In the silver age, literally nothing could hurt him except kryptonite and magic. Even now, after being "depowered" in the 80s, i still gotta give him the edge, because people forget exactly how stupidly powerful he is:
for one, he is physically stronger than goku. I don't care what DBZ canon you use to argue with me. Superman is strong enough to move a mountain.
Superman is AS fast as goku. Superman is canonically as fast as the flash, who uses some sort of bullshit extra dimensional energy force. I say as fast because Goku can teleport... but superman can move so fast that it essentially doesn't matter.
Superman is also tougher than Goku. Im hesitant to point out that Superman flies through the vacuum of space unaided while all DBZ characters use ships because both series have a rather questionable grip on physics. Lets go with this: remember supermans bullshit "ice breath" power? Its not like the dude has power over cold. Its explained as an extension of his overly powerful lungs.
Most of the other powers cancel each other out (Eye beams vs Ki BLasts, Both fly absurdly fast), but remember, Superman also has one more key advantage; he isn't dependent on a reservoir of stored power. (Well, he sort of is in recent continuity. His powers are apparently solar powered, but that kind of irrelevant.)
In any case, this argument strikes me as stupid for two reasons: They are essentially the same character, and as such, if they met, they would get on great. since this is comics, they would probably fight a bit, trade blows so no one is offended, and go kick some monumental ass when it was revealed the villain wanted them to fight so that they might destroy each other.
