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.
Edit: Please be aware that the spyware article on Brave (and the rest of the browsers on the site) is outdated and may not reflect the browser as it is today.
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.
Edit: To the people commenting saying how Brave has a good out-of-the-box experience compared to other browsers, yes, it does. However, this is not a warning for your average person, this is a warning for people who actively care about their privacy and don't mind configuring their browser to maximize said privacy.
That website you link is literally run by a Brave employee. Sure, they might have tried very hard to be independent, but when you literally work on the codebase of one browser you're probably going to write your tests to focus on the things you already know (plus it's not like Brave would allow their employee to run a site that says it's shit, would they?)
Considering how many tests Brave does not pass, I'd say that page looks pretty balanced and fair. Also it is consistent with independent studies where Brave came out on top of the list.
My impression is that most opposition against Brave is largely political. And then people try to find technical reasons after the fact, which simply isn't justified in comparison with other browsers.
By "political" do you mean that the boss is a knob? Because that's pretty irrelevant to the quality of the browser as you say, though all the dodgy things they do like lying about donation money and injecting affiliate links are not.
