Actually, Bitwarden does have its own Watchtower alternative; you'd access Data Breach Report in the menu, and it tells you which accounts need their passwords changed. I'm not sure if it sends a notification when a new breach comes in that includes your account.

Have I Been Pwned partnered directly with 1Password, which is probably why they're able to send out notifications directly; Bitwarden has to worry about being rate-limited.

I'm not too sure what's meant by MFA availability, but Bitwarden also lets you use it as a TOTP generator + use 2FA for logging into your vault, though those are premium features.

Those aren't core to actual password management though. Bitwarden is a very good password manager, and that's what it needs to be to fulfil its raison d'être.

If 1Password's claim to fame is functionality beyond password management, so be it, but that doesn't define it as better but rather broader scoped.

We actually use all those features in addition to password management. Our old password management strategy was an encrypted Excel spreadsheet. This creates problems, obviously. Management, at least to me, mean ACLs, reporting, auditing, and alerting. And that is on top of basic password management.

At least it has a Linux client. 1password cannot justify its price for Linux users when it only offers a browser extension…
