Marvel is far more lax with its cosmological scaling than DC, heralds punch way above their weight class more often with less context involved. Thor's w was legit against Vegeta, Hulk likely should have won against Broly if it's true that World Breaker Hulk scales to Skyfather level characters.
GvS1 was wrong, they somehow got a galaxy-universal character who was quadrillions of times faster than light to be only Brown Dwarf level and a couple times FTL. I'm conservative on Post Crisis Superman and only have him at large star level+ maybe, but you could argue for universe level maybe and perhaps with the highest speed feats he could win as Post Crisis, but overall it was wrong mostly due to how bad they downplay both characters. I would argue Goku's downplaying was more egregious given how much they straight up broke the powerscaling by their denial of powerscaling characters, the gravity formula, and weird headcanon about filler images to get results.
GvS2 was a mistake that was made right as Dragon Ball Super was getting ready to happen. It technically was correct in result (Obviously horribly wrong in analysis, limitless Superman kek) because there was no reason to think movie SSJG/SSJB Goku with only solar system statements from Beerus who he was still weaker than and no DBS to make him universal would be enough to beat Post Crisis Superman (Even if I buy Post Crisis as only large star level+ so far) due to the speed, hax, and experience
GvS3 was correct because Infinite Frontier Superman, compared to earlier Post Crisis, New 52, and even Rebirth (Who was already starting to get really impressive in feats) is simply a different beast who is a composite that beat Trigon and has multiple instances of Source scaling, among other things. There really was nothing Goku could do against the most modern incarnation of Superman, who basically is the very thing Death Battle claimed Superman was in GvS2. They still apparently flubbed up some things, like Miracle Machine scaling and using the World Forger feat as a base feat when he was sundipped in a higher dimensional space. It didn't matter, Superman had too much. I just wish they gave Goku someone he could beat at this stage like Mori Jin, not fun being in the 3 losses gang.
Reverse Flash would shred Goku Black and nobody disagrees with it.
