Since I got on the topic of asking about Vegito vs Gogeta, why not Kefla vs Vegito?
The obvious answer is going to be that Vegito kicks the living snot out of Kefla and mop the floor with her/them.
As it stands Vegeta and Goku as single fighters are more powerful than Kale and Caulifla. Kale has the advantage of tapping into rage which when combined, Caulifla can take advantage of as we seen in the ToP. However, Goku was able to beat them in their fusion form by hitting ultra instinct seemingly, very easily. Vegeta has not reached this level (he may never reach it, who knows) but he and Goku are both able to reach Super Saiyan Blue or "Super Saiyan God Super Saiyan" which those two ladies are not able to reach. Vegito would win no questioned asked.
To make it more interesting, let's remove SSB from Vegito, would he/they still be able to beat Kefla?
