I've used both extensively. At least in my case, my uses are slightly different:
* Docker is nice for consistent development and deployment environments, particularly when I'm on a macOS host and I'm doing userspace programming.
* Vagrant is nice for creating a completely hermetic development environment, both on macOS and Linux hosts. My particular use case has been kernelspace programming: it's nice to not have to worry about accidentally taking my host down. Docker can't provide that kind of isolation, since it's still running on the host (or host VM) kernel at the end of the day.
