The best.

I recently switched over to 1Password Families, here are a few tidbits:

- fast (faster than Dropbox) sync
- easier (compared to sharing vaults with Dropbox) to share additional vaults
- web view for additional functionality, admin console for instance
- easy to setup additional devices

Shout out to Twitter (@1Password) --
The team/person you have running your Twitter account is fantastic. Not only are they quick with a reply, but the reply is accurate and thoughtful.
