This is the key. There are a few projects that can beat it in one way or another, but not all 3. Every project that beats FF in a functional way ends up sacrificing privacy. And those that somehow beat it in privacy are underdeveloped and run into weird compatibility issues or are missing support for key plugins.
According to this Vivaldi protects you from tracking about the same as Chrome and Opera, and both of those provide less tracking protection than even Edge.
Chrome is run by a massive corporation with a reputation for for invasions of privacy. Opera is run by a nation state with a reputation for invasions of privacy.
I’d venture out there and say Vivaldi in functionality and customisation.
Privacy probably not, though Vivaldi does quite well.
Sadly it’s a Chromium browser.
Edit: a simple comparison.

Vivaldi is far better than either of those.
