Each infra is very different, for sure. OpenStack has been rock solid for us, and we have thousands of hypervisors. Granted, we do have a dedicated team, but we don't spend 100% of our time with OpenStack itself.
My comment about people choosing to migrate to the public cloud was more related to the hype of it than anything else. When done well, OpenStack can be better and cheaper, for sure. YMMV.
