I don’t recommend it because there are better options. Firefox is privacy respecting, and since it still has an independent rendering and JavaScript engine, it’s better for open web standards. On iOS, all browsers have the same rendering engine as per Apple’s rules, so I recommend Safari with an ad blocker.
If Brave actually offered something tangibly better for the open web, I would recommend it. But it doesn’t, so I recommend something that does.
However, if you need a chromium-based browser, I think Brave and Chromium are about on par, so I recommend both.
