Goku wins. Ssj3 goku is good to beat lssj broly. And if a ssj3 is weaker than a ssgss then this would make ssgss goku 100x stronger than lssj broly. Goku did take hits from kale in her lssj form but first of all she could have been in rage and goku did not want to hurt her and second of all goku could have been holding back do he is not eliminated and do kale doesn't die .
