I have seen many people in this community either talking about switching to Brave, or people who are actively using Brave. I would like to remind people that Brave browser (and by extension their search engine) is not privacy-centric whatsoever.
Brave was already ousted as spyware in the past and the company has made many decisions that are questionable at best. For example, Brave made a cryptocurrency which they then added to a rewards program that is built into the browser to encourage you to enable ads that are controlled by Brave.
After creating this cryptocurrency and rewards program, they started inserting affiliate codes into URL's. Prior to this they had faked fundraising for popular social media creators.
Do these decisions seem like ones a company that cares about their users (and by extension their privacy) would make? I'd say the answer is a very clear no.
One last thing, Brave illegally promoted an eToro affiliate program making a fortune from its users who will likely lose their money.
Brave has been hyped as a privacy browser despite having several major privacy failures baked into it repeatedly. It's 100% hype. You get the same level of privacy on paper by installing Chromium with an ad blocker and tweaking a couple settings. Firefox has better privacy defaults and is better with an ad blocker installed. Chromium has a slight edge on security (FF needs to really push tab isolation harder) but if privacy is your main concern I would always recommend FF.
