Wow.
I started watching the video but that guys voice is way too irritating to put up with for the next 30 minutes.
Well, the actual simulated fight starts at 16:55 of the video. They used basically every comic (1986 and up for Superman), manga, TV, etc., to come up with a winner, factoring Goku’s magic staff, Kryptonian kung-fu, and Superman’s infinite mass punch. Spoiler: Superman Wins. Long-story short, the sun makes his power infinite. Goku wouldn’t figure out Superman’s connection with the sun to use instant transmission on him.
