It's a matter of preference and threat models. Brave isn't perfect, and has had some controversy in their business practices. They also have some telemetry and cryptocurrency ads. For non-technical users I still think Brave is the best overall bet, especially on mobile devices. There's a great privacy comparison linked in a different thread.
For more technical people, ungoogled-chromium [1] is probably the cleanest option. It's completely free from ads, telemetry, "pings", "experiments", and the like.
More specifically, Brave's clever use of "farbling" is one really neat element of the anti-fingerprinting logic. After all, if a browser just blocks access to certain APIs, that blocking itself could be enough to fingerprint a user. We instead farble the results of certain APIs: https://brave.com/privacy-updates-4/
I am fairly technical and I prefer Brave because of the ads. It's the one model I think that has acceptable ethics and that can be an alternative to Surveillance Capitalism. Crypto is just an implementation detail, but an important one if you really want to make it a global alternative and that can include the unbanked.
It made me contribute to content creators way more than I have with Flattr (now owned by scammy EyeO, remember them?) or with Patreon. I can not do any of that with any other offering.
So it's sending some amount of telemetry, but it's not so bad compared to mainstream browsers. A more detailed comparison is available in this report linked by another commenter: https://www.scss.tcd.ie/Doug.Leith/pubs/browser_privacy.pdf
