Recommending Brave is not easy. They bloat their Browser extremely, community support is not existing. I asked them where to place Brave policies on Linux, and got no answer after weeks.
So it can use Chromium policies and you should absolutely use them, have a look at secureblue for a reference implementation.
Brave is bloated, but these elements can be disabled and possibly also not compiled, which I will try to do. They do seem to care about privacy, but at the same time the company and CEO is EXTREMELY shady.
They also plan to resist the mv3 enforcement in the future, which means they may need to lack behind a lot on security updates.
On Desktop I would always use Firefox instead of some Chromium fork. And as explained above, also instead of Chromium, which always sends data to Google no matter the settings. And also, Firefox takes security serious and their implementation is different and for sure less documented but saying "it is less secure" is a huge oversimplification.
On Android this is not the case very likely, where there is urgent need to improve. No idea about IOS, especially as its just now a real Browser and not a Safari frontend.
