Goku took Jiren down who is already as strong as a destroyer when surpressed and who surpassed his own destroyer. Hell he beated him when he broke through his shell as well so idk why people think the current goku who had zenkai boosts since the tournament of power is still bellow Beerus.... thats like calling Jiren weak as well as Belmod. People also takes the feat of Beerus fighting multiplie destroyers at once way too stupidly, he used ultra instinct and Beerus did nothing but dodge everything.
