I have Sigma Rild something above Gotenks Boo Kaioken x2. The first can win, because despite the slight advantage of Gotenks Boo over Rild (in terms of techniques), it is eliminated considering the tension of the Kaioken x2. Therefore the slight advantage of Sigma Rild over Gotenks Boo Kaioken x2, allows Sigma Rild to win with high difficulty.
According to my numbers, Cabba SSJ2 (ToP) is a bit more powerful. Goku SSJB (ToP) is at least 10x stronger than in the Tournament Universes 6 and 7. Apparently, the gap between the SSJ on the Base of the Saiyajins was reduced considerably, so perfectly, Goku Base (ToP) is 100 -200x stronger than Goku Base (Tournament Universes 6 and 7). Goku Base (ToP) is only slightly stronger than Caulifla Base (ToP). Caulifla Base (ToP) is very slightly superior to Cabba Base (ToP). Goku SSJB (U6) can use an Infinite Kaioken if necessary.
Kefla SSJ runs the Guantalete of the SSJB Kaioken states of Goku (U6).
Goku SSJB has no tension with any level of Kaioken.
Kefla SSJ recovers after each fight won.
What level of SSJB Kaioken does Goku need (U6) to defeat Kefla SSJ?
When Goku defeats Kefla SSJ, Kefla recovers and transforms into SSJ2.
What level of SSJB Kaioken does Goku need (U6) to defeat Kefla SSJ2?
