Goku is much stronger than Beerus, or at least it should be according to author Akira Toriyama. In fact, not long ago, an old interview appeared that dates back to the release of Dragon Ball Z: The Battle of the Gods, in which the author commented on the power levels of Goku Super Saiyan God, Beerus and Whis.
The interview in question was recently translated from the guys Kanzenshuuand confirmed that while speaking with a reporter, Toriyama found the following: "The strength of the Super Saiyan god? Well, if Beerus is a 10 then I would say Goku Super Saiyan God is roughly a 6. Whis is instead a 15. The Saiyans are fighting harder so after many battles they may be able to fill in the void".
According to the author, the Super Saiyan god possesses a strength that is just over half that of the god of destruction. The Super Saiyan God Super Saiyan, also called Super Saiyan Blue, it should therefore be able to match Beerus' level of performanceif only with the help of the Kaioken. At this point it is impossible to know whether Toriyama was referring to the Beerus in the film or the real Beerus we saw against Zamasu or against the other gods of destruction during the Tournament of Power, but regardless of the context. There should be no doubt that Goku Ultra Instinct can beat him more or less easily.
Of course, it's always possible that the author was referring solely to the anime, or that he chose to change the skill levels in the race, but according to him, Goku should be - at least for now - the strongest warrior after Whis. Plus, Beerus never achieved Ultra Instinctand Goku UI managed to defeat Jiren, a fighter as strong as a god of destruction, fairly easily. For now, the balance seems to be on the Saiyan side.
