For me there is a tradeoff. On one hand, Bitwarden's online offering where you trust them with your data is convenient, but also a single point of failure. If their server goes offline, you can't access your passwords (And servers do go down). On the other hand you can repair your own instance if it goes down and have full control over it. The only caveat with self-hosting being the overhead. Regular non-techie people just don't have the time or intellectual curiosity to experiment with self-hosting. For me personally I just sync a Keepass database with Dropbox and call it a day.
