Stop kidding yourself
This all relies on trust. These are two companies both trying to sell you into trusting them for profit. If you are surprised when any of them turn out to not be as trustworthy as they try to pretend, you're a fool. This is the internet, there is no such thing as genuine privacy. Not with a VPN. Not with the US defence force owned TOR.
It was also very funny for Brave to stand up on a soap box talking about their competitor then when it comes to questions about the website they point to being owned by their employee they go "hey, trust us". Expect companies to put profit before your benefit.
