I used to be a Chef user, and although I do love it, it's overkill for the current infra I am supporting. I haven't had too many issues with Ansible, I love it's simplicity, just lately there have been some annoying regressions.

I do really appreciate that testing is a priority in the Chef community, cause it definitely isn't with Ansible. It also seems like based on the naming conventions in the Chef cookbook, that Ansible is playing catchup with 2.1 (imitation is the sincerest form of flattery?)
