I've just recently started to use 1password and here're my thoughts:

- Amazing support and fast response on their forums from the reps

- Works across Linux (my desktop), Mac and iPhone and Safari and Chrome browsers

- Has CLI

- Syncs instantly (unlike Chrome and iCloud Keychain)

- Supports TOTP (no - it does not completely defeat the purpose of 2FA, there are multiple aspects to it)

I am also aware of the risk I'm taking by trusting a 3rd party commercial company with my credentials.
