1password has better UI/UX and is faster but Bitwarden is cheaper, supports prompting of the master password for specific passwords, and better security options (such as app idle settings instead of just device idle)
I started paying for 1Password years ago when an annual family plan was $48, and to their credit, they've kept me grandfathered in to that price this whole time.
1P is closed source and have had a number of breaches in the past. Bitwarden have had none that I'm aware of, and they're FOSS. I however have been preferring ProtonPass lately (also FOSS) and really like the layout over BW.
Do you have a source for this claim of multiple past breaches? The only one I know of is the Okta breach.
For me they're still firmly in the 'one of the best options out there' category because cross-platform usability is incredibly good imho. I will admit it's been quite a while since I migrated from KeyPass so maybe these other options have improved too.
This is either ignorance or throwing shade at 1Password. Outside of their Okta thing (which didn't impact vaults as far as I'm aware, and was more Okta's fault) they never had a compromise. They are definitely an excellent provider.
I might be that guy soon. I really don't like Bitwarden's extensions, they have clunky UX, are slow and often don't even respect my settings. Autofill is a crapshoot, especially on Android. And they have performance issues with the Firefox and Chrome(-based) extensions so it's not even platform specific.
I've been on 1Password for years and am wondering if I'm missing anything.
