I switched to BitWarden for a while when it looked like 1Password was going to be in-browser only as the future on macOS, and one of the major things for me was it making logging in to multiple Google accounts harder than 1Password - it seemed to always be presenting the wrong password as a default, whereas 1Password would just get it right.
