That is what I am curious about, too: starting the the v8 of 1Password I just can't justify paying premium for 1Password anymore as a mac user who has a family account. Both have Electron clients and cloud-only vaults, but Bitwarden subscription is 40USD/yr., and 1Password charges 60USD/yr.
In my opinion 1PW just lost any advantage it had, at least for non-business users.
