You’ve used onion links. Brave implemented unsecured onion protocol in thier Chromium browser.

Anything using Firefox as a base can run onion links with a simple add on because Tor is just Firefox. Vivaldi comes with onion support right out of the box, doesn’t support hate and is malware free.

I use brave and think it’s the best browser available, so I’m not arguing against it or anything, but technically it just supports use of the onion protocol, it does not provide the same full suite of protections that the tor browser does

As Brave says themselves:

For users who currently require leakproof privacy, we recommend using the Tor Browser, which provides much stronger and well-tested protection against websites or eavesdroppers using advanced techniques to uncover a true IP address.
