Puppet is great for central control with automatic runs making systems
right and keeping them in line, it's not an orchestration tool though -
however it's commonly supplemented with something like rundeck and/or
mcollective to assist here.

Chef is great for a ruby house - you'll need to brush up on your ruby as
writing cookbooks is heavily tied to the language. Historically it was very
debian focused with issues like selinux problems. I believe these have been
generally resolved though.

Ansible is a great orchestration tool and excellent for going from base to
a configured system. It is less of a tool to keep things inline with a base
however with no central automated runs (ignoring Tower which is not FOSS
yet).

Ansible is also much simpler to get into given the tasks are just like
following through a script for defining how to make a system, as opposed to
learning an actual DSL like required for understanding puppet modules.

There's a growing pattern of using ansible for orchestration alongside
puppet for definitions as well (there's a specific ansible module to carry
out a puppet run).

I've not looked at salt at all personally.

Came across this article a while back:
