LastPass would sometimes post to the wrong login form.
1Password got confused a couple of times between 'Logins' and 'Accounts'.
With 1Password, when I'm away from my computer, I have to use my phone to read my passwords. If my phone dies (fairly common) I have to install the password manager (not always possible).
With LastPass I can access their web interface--but experienced too many of the issues above. Plus I am a little nervous about a 3rd party having that much power.
I'm sure all of this was my fault, but the end result was I discovered many hidden costs and it felt like I was fighting against them.
