Possibly, at least for my own experience. It's much less often that I rerun a search with !g. Brave Search's results are becoming more relevant to my own queries, and Google's becoming less so. Not to mention how ads like to masquerade as ordinary Google results; using Google is starting to feel less comfortable.
That seems to be the general case, other search engines. Especially Bing and those based on Bing are yield increasingly good results, while Google is just ads and spam.
