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.
