Ask HN: Do you use Vagrant or Docker for active development?

I think I understand the use case of Docker for deployment, but does Docker hold its sway at the moment for active development. Data persistence support is not out-of-the-box. Vagrant with its own isolated and shared volume support seems like something that would be very good in active development of software artifacts. What is the view of the HN mass, and what would you recommend?

Apart from these two, are there any others that looks promising?
