Superman would beat goku. First off Superman holds back alot. Secondly superman is way faster than goku. I know many are gonna argue instant transmission, but superman can move at speeds of light. Thirdly goku had trouble lifting an entire city in gt. Superman has towed entire planets on a chain. Goku could destroy the sun yes, but that mean he would kill everyone else in that solar system something goku would not do. Goku could realize kryptonite would weaken him, but he wouldn't do that either as Goku wants to fight his opponents while they are a t full strength. Superman will exploit a weakness to win. Don't bring up gogeta cause gogeta is goku + vegita, or vegito as that is much the same. I mean Foku is my boy too, but I know comicbooks as well, and well Goku would have trouble with Hulk let alone Superman.
