Story wise, Goku just got a major upgrade this year. He is now way beyond what he was during the DBZ saga. He is now even way more powerful than GT's SSJ4 Gogeta which is non canon, btw. He is now a Super Saiyan God Super Saiyan. His base power is now Super Saiyan God and so far, he was shown to reach SSGSS level 1 (blue hair). He can keep teleporting between planets and destroy each and everyone in the Destiny universe one by one in an all out fight.
