I’ve been hearing this a lot. I’ve been asked a lot that who would actually win if these two super bodies were to face off each other in a death match.

so i thought let’s put this discussion to an end.

with the simple and quite easy to guess answer for the believers.

It’s “GOKU”

and for all the non-believers here are some points we’ll be using to compare:-

1. Speed-> Now every one says Superman can go upto the speed of light and Goku can’t. Which isn’t true at all. First of all Superman can go upto light’s speed that’s also half true because he can only achieve that speed while flying but on foot he can’t.he couldn’t even beat flash in a race who admits that he runs at the speed of light. Moreover Superman just has a  raw speed of flying around as he’s never faced an enemy of his level of speed or strength so he just goes and bang them all, the fact that the worlds best martial artist could do to him is still unknown. On the other hand talk about Goku’s speed, I” just say two words Instant transmission. Well that wouldn’t be fair now, would it? So Let’s talk about Goku’s Flying Speed. For an instance In The Movie  When Goku Fires a kamehame to redirect coolers deathball back at him. It took 27 sec in all to reach the sun, Now accordingly Earth’s Distance From Sun is 149,600,000 Km
   therefore Speed->149,600,000/27=5,540,740.7 Km/s
   Almost twice the speed of light. and anyone who can doge it will obviously need to move even with a grater speed just to have an reflex action or to even see it. And that was just Super Saiyan 1 and he goes way up to 4.
   So Superman Wouldn’t even have a chance of having  a chance here.
2. Power-> Talk about power, Superman is the strongest in the world I’d give him that. For instance he was easily able to lift 200 quintillion tons. But that was only when he was thrice his original power so actually it’d be 200 quintillion / 3 that is 66.67 quintillion. Which actually is something. So superman really is the Strongest. But for a real comparison let’s break him down in terms of power level.
   I used power level as a way of how much damage could be done to a certain amount of mass. New 52 Superman is accurate by him benching the Earth for 5 days. A power level of 15,000 is require to destroy the Earth. 24 hours x 5 = 120. Now 120 x 15,000 = 1,800,000.
   All-Star Superman is accurate by his one arm 200 quintillion ton feat. The Earth is 6.580 sextillion tons, so wait he’s much weaker than his posted power level? (facepalm).
   Recalculated 1,950,000
   Good call I’ll need to recalculate that. But for Superman Prime, he is a super sun dipper. Lets say he has the full power of the sun. 1.295 million Earths can fit into the sun. 1.295 million x 15,000 = 19,425,000,000. So I need to fix All-Star Superman
   Now Goku is the strongest in the universe, There is no raw instance for Goku’s strength but by the end of the Frieza saga Goku’s power level was about 150,000,000. Now this is  just super saiyan 1. Enough to take out All-star and New 52 for good. Now Goku said that hyperbolic time chamber gives a power multiplier of 3 so when vegeta got out it’s assumable that his PL is 450,000,000. Later, when Goku comes out and powers up for korin only up for 50% it alrms Vegeta and Gohan so it’s safe to assume that his PL was 900,000,000 by then.
   Then you get into the Buu saga. SS3 is another x4 on top of SS2, so assuming Goku didn’t get any stronger in his 7 years of training, that puts him at 7.2 billion. I’ll come back to the Buu saga later, because there’s more points to be made there, but I’ll skip ahead to GT for now. In GT, Goku becomes so powerful that he is easily a match for Super Perfect Cell, in his base form. SS2 Gohan was roughly equivalent to SPC, so base form GT Goku equals at least 1.8 billion, but likely much higher. Now to account for SS3, we simply multiply his base power level by x400. That puts SS3 Goku in GT at at least 720 billion.
   That would be more that enough to take out more than 36 supeman at a time.
   Still going further to SSJ4
   Supreme kai states in episode 219 that he is 1000 times stronger than Frieza. As you already pointed out, Frieza = 120 million, times 1000 and you have 120 billion,Boom.
   In the Super Exciting Guide, on page 63, it states that fusion via the earrings is in fact multiplication of power levels. That means Kibito Kai has a power level of at least 14.4 sextillion.(21 zeros)
   Now it’s also stated that during Goku and Vegeta’s fight with Buu in their base form, Kabito  Kai would just be coming in their way.
   that gives Goku and Vegeta > 14.4 sextillion.
   Either way, that 14.4 sextillion can still be scaled up to account for transformations, including SS4. That puts SS4 Goku’s power level at a staggering 57.6 septillion.(24 zeros).So that concludes it.
   Goku Kills.!
