poubellier Brave is a fine choice. Brave has anti-fingerprinting measures that will fool naive scripts. If you need something more than that, you should consider using Tor Browser.
One killer feature that puts Vanadium above Brave from a security perspective is the fact that JIT is disabled by default, and there's a per-site toggle for sites that absolutely require it.
A lot of vulnerabilities hinge on JIT being enabled, so having it disabled is a huge boost to security. Apple's lockdown mode also disables JIT in Safari. It's a very important feature.
