You'll have to add some actual reasoning to this, I switched from 1password to locally hosted Bitwarden(Vaultwarden) 6 months ago and I don't miss anything.
Does Bitward have anything like 1Password's "Travel Mode" where you can hide specific vaults, for when crossing less-privacy-friendly borders? Also, is it possible to share credentials with a link/URL? These two features ended up being much more useful than I thought when they first launched, and looking at Bitward I don't see anything like those things.
You can share credentials I do with my wife. Not sure you can hide vaults though. I never used that on 1password.
