Just anecdotally, I've had the shittiest experience in recent memory with CoreOS. Their choice of BTRFS bites me pretty much daily whenever logs start writing stack traces for errors. A similar problem happened when Deis chose CephFS for their registry container.
While I'm a huge fan of Docker I will maintain that CoreOS is not ready for production in most capacities and recommend against using it in its current form.
