I do agree on many of your points and I used to use Brave before certain deal breakers. I personally have in addition mulch, cromite, and Privacy Browser for mobile so i can try different options. On desktop, gecko browser are much more comfortable, but i have the ungoogled chromium flatpak browser with ublock. Mozilla has a better track record than google for privacy and is big enough to have good security and updates, and often disallow features that would compromise privacy, that otherwise chromium accepts iirc.
