For the past two years people has said SSJ2 Kefla is stronger then SSJB Vegetto( Black Arc). And here's why that's false.
At the moment of Gattai Zamasu's fusion it was stated that his power expanded to no end( it doesn't matter just wanted to state it). During his battle with Goku & Vegeta, Vegeta says" God or not, I've never seen anyone let of energy like him" this would also include Beerus since in the training arc they say Beerus unrestrained, and this is Zamasu toying with them. Then Shin goes on to state that Zamasu's standing as a god was beyond their understanding. Now taking all this we can assume Zamasu is Beerus level or at least close to it maybe even past it(Not head cannon what I gathered from the show's statments). Now in come Vegetto who we saw was equal in power to Zamasu showing that Vegetto has the same standing in power to compared to Beerus as Zamasu. And to those who say Trunks was stronger than Vegetto is not true as it was stated multiple times that Zamasu's body was falling apart.
Now in the Tournament of Power ignoring that Goku was "rusty" compared to him in Black arc. Both Vados & Champa were both unsure if Kefla could beat a full stamina Goku. Now some say that SSJBKK was stronger than Goku cause he got some kicks in which doesn't make sense cause by that logic KKx20 Goku was stronger than Frieza in Namek saga cause he got some attacks in. But this is both Vados and Champa saying she might not be able to win. There are also people saying that Vados was saying she kept getting stronger which is also false she said" Kefla's power consists of Caulifla and Kale's power multiplied tens of times." and when fighting UI Goku she said Kefla's attacks were strong and fast but Goku's reflexes are still superior.There also the statement that in Goku final use of UI Beerus thinks that Goku has surpassed him, meaning that the first two times Goku wasn't even Beerus level, so Vegito is stronger
Now my last arguement, after Vegetto defused neither Goku nor Vegeta were able to transform, while Caulifla was shown to transform a few minutes(their time) after defusing.
There's probably more but I can't think of them right now.
