The main reason for people repeating "uBlock Origin + Firefox is best" is because CNAME uncloaking didn't work on most Chromium browsers, even on Manifest V2. It does on Brave.
AdGuard works better simply because there's a bunch of people being paid to work on it. There's more optimization and less bugs. The UI is a whole lot more polished. Blocklists have improved syntax, and the lists themselves are updated more frequently to catch site breakage. EasyList often has breakage on their lists for months even after being reported on their Github, but reporting the same breakage to AdGuard results in the breakage being fixed in days if not hours. And they do adjacent projects like AdGuard Home (sort of a commercial Pi-Hole) too.
FWIW, big names in adblocking work for these companies too. AFAIK, FanBoy (EasyList + EasyPrivacy + his own lists) gets paid by Brave to maintain the lists. So in a way, Brave is funding adblocking for everyone :)
