I like Goku way more than Superman, but everyone that thinks Goku would beat Superman is very misinformed and very likely has little knowledge of Superman himself. The strongest Superman has become to date is Superman Prime, who is essentially omni-potent.
He spent 15,000 years saturating inside of a sun, he has the last and most powerful green lantern ring.
Superman Prime's vision is now God-Like allowing him to see everything in all of time and space, the distant past, and the future, which means he can see everything Goku is going to do before he even does it.
Because of the powers Superman obtained from the Source, he can alter Reality on any scale he wants, from Universal to Multiversal scale.
He has gained the power of the 5th dimensional imps, for those of you that dont know, the 5th Dimensional Imps, are Imps... from the 5th Dimension... go figure. They are beings with extreme power at their disposal that put them above nearly all cosmic beings in the Multiverse. They have shown to be able to destroy dimensions by laughing and creating entire Universes by snapping their fingers. So if Superman wanted to he could destroy the universe that Goku is in thus defeating him.
Not only can Superman now teleport wherever he wants (Instant Transmission) he now has nigh omnipresence which means he can almost be everywhere at once.
He is now nigh - omnipotent which means he has power over almost everything as well as being invulnerable, he is now immune to kryptonite.
There is no way Goku can win a fight against him. Even if they were somehow evenly matched, Superman would simply out live Goku during their fight.
