From 70% leaders onward, SSB Goku is better than SSBKK Goku at the same Super Attack level and potential activaion. But under VB's 50% leader skill it's different. SSBKK's passive amounts to about +100% ATK & +110% DEF maximum. He also has much better links than SSB Goku, especially for Vegito Blue. So I think SSBKK wins out under PHY Vegito Blue but not for higher percentage boost leader skills. AGL SSB Goku + AGL SSB Vegeta >>> SSBKK Goku in the long run.
