I run my own DNS so can easily see attempts to phone home, and serve ads. I get less of both those things than I used to get with Firefox and its 'Sync' routine. I feel more secure with Brave Browser than I do with Firefox but I have no axes to grind and am perfectly happy using Firefox onsite when it is called for. Little performance differences. Marginally, Brave is better.
Bias is real, does not demand bigotry, and is sometimes existentially beneficial.
I've mostly been using the chromium-based Brave Browser which is Chrome without the advertising engine plus a built-in adblocker. Requires going through the settings once to enable that. There's a very decent android-only browser that does much the same, called Bromite. (Brave has a mobile version but Bromite is developed from scratch for Android, and is stable & supported).
I hope this helps someone.
This was last July? But in any event the article which was updated soon after original publication says oops, nevermind.
