For myself, mostly using KeePassXC. ProtonPass exists just as a backup for extremely important accounts, in the event where I somehow lost all of my KeePass files stored on all my devices lol.
That said, I do agree that Bitwarden (or most other clients) is probably way superior than ProtonPass itself. I do wish that they had focused on improving their other applications (Mail, Drive. VPN), rather than try to compete in the password manager space...
For my own stuff, I do prefer Bitwarden over Proton Pass. Simply because having a lot of stuff in Proton and if then ending up being locked out feels like a too high risk.
I even have some stuff in https://www.passwordstore.org/ where it's synchronised to some (encrypted) locations and internal storage servers ... especially stuff which can help me if I get locked out of Bitwarden.
Don't put all your eggs into the same basket. Avoid the SPOF.
That said, for Proton accounts where I'm the admin - I would recommend Proton Pass these days, as it provides ease of convenience. Where less technical users has only one "platform" to relate to. If these users gets locked out; I have a chance to help them recovering again.
