I've tried both Puppet and Chef. Puppet fits my mental model more, but I had for more success with actually getting Chef up and running.

Puppet, on the surface, has less 'messing about' to do in order to get things running - but my experience was that I encountered a few issues which basically caused me to spend way too much time mucking about rather than working.

Ideally I would like to use Puppet, I feel like it's cleaner and it seems more 'logical' to me at least - but I only have actual experience of Chef working, so make of that what you will!

Once Chef is up and running, it absolutely flies, which is always good!
