I personally think it's a pretty good password manager (like all others, database sync is a problem for users to solve). I had been using its Linux port -> keepassx (also available for macOS - yes NOT Mac OS X any more...)
I switched to pass / qtpass (cross-platform Qt frond-end for pass) after seeing it on hacker news (or somewhere else like Twitter) because it uses GnuPG + git (simple and I am capable of both in CLI). Last but not least, pass provides migration scripts from keepass/keepassx (and a lot more... - feel like I had to migrate ;-)
