After daily driving it from march to now i can say that in term of user experience it's great ! On the privacy side it's better than firefox since it disable telemetry by default and offer a really good container tabs integration but far from librewolf with resist fingerprinting on.

The team is smaller and has made mistake in the past ( leaving remote debugging on in a release ) but it's nothing egregious for me and I will continue to use it in place of firefox/librewolf.
