Brave Browser

I'm a Firefox fanboy admittedly, but for a few reasons, I've been using Chrome for the past few months.
had some small glitches with the Google Account and syncing, anyways, have just started using Brave this week.
have put it on my mobile, home and office PC and I have to say, I'm liking it - at lot.

just throwing it out there - does anyone else have any first hand experience using it?
pros, cons, pitfalls, feel good stories???

been out for a while I think, like a couple of years.
has about 50 million users they state.

I'm liking it a lot and am thinking "that can't be right - what's the catch?"

I have my own HTML code as my start page (home page) and the javascript code and HTML code always show slightly different on every browser I have ever tried, add to that syncing across devices, privacy, extension support, and web site support and so far Brave is ticking every box - something I have never seen with all the browsers I've ever taken for a spin.

I'm hoping someone can chime in with their experience so I could get a real world view.
