I've been using 1Password for a few years now. I'm not qualified to comment on the security aspects of it - I'm trusting them and Apple to take care of that.
But I can comment on the superb quality of the user-facing aspects - it's a pleasure to use, has great iPhone and Dropbox support, and I really like the way they communicate as a company.
