I consider them more insecure than a reasonably well made password manager, all that is between you and any possible site you will ever register on or have registered on, is a master password. On the other hand, I can change my Lastpass/Keepass password regularly, denying a cracker access to my accounts in the future. The security of any password manager, including hashers, is not only how secure it is against attacks, but how secure it is after it has been successfully attacked and how easy it is to recover full security without losing too much data.
