I’ve never used Proton Pass so I can’t comment on which is better. However, my wife and I have both used Bitwarden for a number of years and have no complaints. Works with Brave, Chrome, Firefox; works on Linux, Mac and Android. We don’t have Windows or iPhone so can’t comment on those. We can share selected passwords between us.
And it all just works.
SLS (Softlanding Linux System) was my first.
