Any arguments for Brave are short-sighted given that (at this point) if Firefox goes we lose the whole battle for open web standards.
I do believe that Firefox is the best browser, but even if it wasn't it would have to be significantly worse than the others for me to justify not using it.
Brave for the compatibility with websites (because most website designers are testing against Chrome), out of the box it's hardened for privacy, and we'll play DRMed content when you need it to.
Though I have heard nice things about Vivaldi as well. I may look at that in the future.
It can be a hard road to stubbornly refuse to follow the path of least resistance. But it is vital that as many as possible forge alternative paths or the path of least resistance (Chrome) can become the ONLY path.
Ah my apologies. I'd say Brave out of the box then. It has Google's DRM blocked by default and I would see them continuing the trend, making it more opt-in. Time will tell.
