Brave's adblocker won't do anything against Google's trackers if Google builds it in to the engine.
Again, I advise against trusting anything Chromium-based.
Also, you apparently haven't heard of uBlock Origin's Medium Mode. Brave can't even touch that. There's more than just advertising to worry about on the web.
I use too, but is not without its problem. It does implement a lot of adds in things like the new tab page, and it did some controversial stuff (they use to replace page ads with their own, essencially stealing the page monetization, dont know if they still do).
For a while Brave is going to be my stop gap browser. Hopping that Ladybird can soon replace it.
For all its flaws, Brave still annoys me less than Mozilla assh*les.
I also tried Zen Browser... lovely, but is pretty much Mozilla with a bunch of addons. The problem is, is not clear how much of the invasive Mozilla telemetry they left on their code base.
Unfourtunally, any browser that orginates from mozilla bullshit, for now, I kind consider fruit of a posionous tree.
