Honestly, Ansible. I spent a week on Puppet a couple years ago, and was barely making progress. (Disclosure: I'm not a Ruby developer and only have basic understanding of that language). I picked up Ansible in about one hour and already had a server's setup automated by the end of that hour. Now I automate 99% of everything using Ansible... and it's not much more complicated today than it was when I started.
