Brave is interesting. Built-in ad blocker even on mobile. Not as good as uBlock Origin on Firefox but it's an option.
It also has its own advertising platform. The ads are simple notifications, no bullshit. It actually pays users in cryptocurrency for their attention. It can also be completely disabled.
Not sure the world needs another ad-monetized browser. We need less ads on the web, not more. And what is the point of shipping a browser with an ad blocker only to serve your own ads built into the browser?
My personal experience with it is that it is slow to start, bloated, the ad-blocker doesn't block Google ads by default and it fills home screen with some kind of crypto sites by default. It looks like it is trying to be a general purpose browser but judging by the choice of default options it looks more like a very niche browser for the crypto community.
The most innovative thing they have right now is Search, hopefully it doesn't end up being ad-monetized too.
