I’m not sure it will work out that way.
Brave will face the exact same problem an add-on or extension will. When they say ad blocking is built in, they’ve just compiled the binaries with specific addons baked in. So your experience with ads will be the same as anyone using chromium + ublock lite, or vivaldi, or whatever else.

I’ve been a firefox supporter since netscape.
That said, things aren’t going great.
Because it’s market share is in the toilet more and more web sites just aren’t supporting it any more. My university’s website, some government websites, and 2x industry platforms I use for work just plain do not work in firefox.
Mozilla just bought an advertising company. They can spin it as they like but basically, mozilla’s primary revenue source in the future is going to be ads.
They just had a throw down with the developer of uBlock. I don’t think this is particularly meaningful, but it’s not a tick in the right column.
