I use 1Password due to convenience. I'd happily go with an open source format and whatever implementations exist for different desktop and mobile operating systems, but these are often lacking in terms of ease of use and user experience and are therefore not the best option should I want my relatives to make use of them as well. 1Password passes the litmus test which is getting my wife to actually using the password manager that I installed her. I didn't have much luck with open source alternatives.
