Personally I have found openstack-ansible to be robust and very useful for a production environment. Not only the tool itself but also the help offered by those whose develop and use it. There is a bit of a learning curve however. At the end of the day I think the best solution is the one that works for you and if you have a chance you should try each one to see which is most suitable. I have not tried TripleO, Airship in a bottle did not work out the box, Kolla-Ansible is useful also but gave me fits troubleshooting, and OpenStack-Ansible I mentioned the learning curve. I do not deal with a lot of manual deploying these days but if I was spinning up a public cloud personally I would roll with OpenStack-Ansible
