Personally, I prefer SSGSS Goku because he doesn't sacrifice HP, he has a percentage boost passive, and also because mine has two dupes while my SSBKK Goku has none, but in your case SSBKK Goku would be better. On a Super Vegito team he doesn't sacrifice as much HP as he would on SSJ4 Vegeta team, and more importantly you need his links.

Plus, it's best to use SSGSS Goku alongside SSGSS Vegeta (on JP they get +2 Ki and +65% ATK when dokkan awakened, while on Global they still get +2 Ki, +40% ATK and +1900 ATK, because they haven't updated a few link skills yet).
