don't get me wrong Death battle has been really good to but they never put PL units into this
scientific proof people!!
I have seen the death battle. while the numbers are slightly in super man's favor I still doubt he would win. while super man is used to fighting people weaker then him and sometimes just as strong as him he doesn't have the fighting experience goku has of fighting someone stronger then him or fighting as often against his equal. super man doesn't have martial arts. while super man does have the strength on his side he doesn't have anywhere near the firepower for distance attack and goku would read that early on in the fight. the fight would never be to the death. if it was then goku would lose just because he can't breath in space and the planet they are fighting on would surly be destroyed. it's been a while since I read this but I remember someone quoting Stan Lee that super man would lose to goku.
that is not supermans maximum strength not even close to a Google search after being saturated with yellow sun energy he was capable of lifting 200 quintillion tons (that's 200 billion billion tons) with one hand he and he said he felt like he could lift even more the machine simply couldn't exhibit more force against superman
