If you're happy with Bitwarden, I think you should stick to that. I'm currently using 1Password, I switches after the security issues with Lastpass. Later I did try Bitwarden but was unhappy with the ability to correctly identify username and password fields on websites. Others tell me that they have more a better experience with Bitwarden, so I might have to give it a try again.

1Password is really nice, but it's also expensive, compared to Bitwarden.
