How much have Goku and Vegeta improved since the U6 Tournament?

[GSM123]

Some believe they've made little to no improvement, some believe they improved a lot based on Vegeta's fights against Black... So, have they gotten stronger or did they just improve their transformations? If yes, by how much?

 

[Captain Cadaver]

I wouldn't say they should've gotten any stronger. The focus on the statements with Vegeta's rematch with Black was upon being able to instantly switch between God and Blue rather than any training gains, with his little to no improvement in strength being supported by Goku doing as well, if not better, against Merged Zamasu.

And what about SSJ2 Vegeta kicking Black's ass? Don't you think that could mean he and Goku improved between Trunks' arrival and their fight with Black?

 

[Captain Cadaver]

I'd say that just suggests either the SS2 Vegeta > SS3 Goku chain from BoG remained the status-quo or Vegeta mastered and improved upon the enhanced version of SS2 Trunks used prior. If Vegeta had made such massive gains in such a small amount of time, Goku or Trunks would've definitely noted such.

A new magazine says that Trunks used regular Ssj2 against Goku so there's no such thing as Evolved Ssj2

Vegeta got far stronger, I have his base superior to Chapter 19 SsjB Vegeta mostly due to this:
