Have you used both jails and Docker? Saying docker is a much more polished option doesn't match my experience. Yes, it has more features, but with these features come more bugs. Some of them are minor annoyances. Some are of the "our infrastructure is fucked until we switch our storage driver" kind.

Sometimes, stability is a gain.

I'm not comparing Docker and jails, I'm talking about things around. Stackoverflow.com coverage, blogs posts and guides, github repos, publicly available images, etc.
