Agreed, to actually convince anyone who uses it to switch over to another one I would have liked to see an objective comparison of how solid the privacy features are on both browsers, that's the only relevant argument that matters to anyone regardless of their ethical beliefs, here the only thing that tarnished Brave's reputation for privacy was the injected affiliate URL parameters, that's pretty bad, but it has also been fixed since, doesn't mean we can blindly trust Brave now, but it's not as bad as it is made out to be. To make a counterpoint, I think it's good that there is a privacy focused Chromium browser, because they can take a stance against proposed Chromium changes, like the handicapped ad blockers under manifest v3 or the most recent WEI, Chrome still goes ahead and implements those, but Brave remains and keeps their Chromium saner.
Personally I barely use it, but for what I have seen it has its ups and downs, if we also bring who's behind the product into the picture then even Mozilla hasn't always done good and good alone
