Can you show me how it's not safer? Not trying to be snarky. Genuinely curious. Brave uses its own index for searches and blocks ads and trackers and doesn't create a user profile of you. As for the Chromium bit:

Brave is built on top of the excellent open-source Chromium project, the same browser engine that also powers Google’s Chrome and Microsoft’s Edge browser, among others. While the Chromium base is an excellent foundation for a web browser, there are lots of ways we feel it is not privacy-protecting enough by default. Brave’s goal is to protect users’ privacy by making many changes (and subtractions) from default Chromium, including disabling or removing privacy-harming Chromium features, proxying communication with Google services through Brave servers, and reimplementing sync to be encrypted client-side and never touch Google’s servers. All of these changes help prevent Google from tracking your browsing behavior.

So they claim they've taken the best parts of google search engine, made it their own and don't rely on google in any way. Of course this is what they claim. I get it if you're skeptical of any search engine, regardless of what they say. Google is still the superior search engine, but Brave seems like the best alternative I've come across. Just my two cents!
