Leaving containers vs VMs aside, docker for Mac leverages a custom hypervisor rather than VirtualBox. My overall experience with it is that it is more performant (generally), plays better with the system clock and power management, and is otherwise less cumbersome than VirtualBox. They are just getting started, but getting rid of VirtualBox is the big winner for me.

It's based on the OS X sandbox and xhyve which is in turn is based on bhyve https://blog.docker.com/2016/03/docker-for-mac-windows-beta/
