New Openstack Deployment questions

OpenStack deployment questions: If you were starting a new deployment of OpenStack today what OS would you use, and what tools would you use for deployment? We were thinking CentOS with Kayobe, but then CentOS changed their support plans, and I am hesitant to start a new project with CentOS. We do have access to RHEL licensing so that might be an option. We have also looked at OpenStack-Ansible for deployment. Thoughts? Thanks in advance. -Tom
