Cfengine vs Puppet

Hi there,

I'm currently working on comparing the differences between Cfengine and Puppet for centralized systems management. Do any of you have experience with either? We currently have Cfengine2 implemented, however we need to upgrade to either Cfengine3, or Puppet.

I'm looking at Puppet as an alternative since the upgrade from cfengine2 to 3 has essentially rewritten the syntax.

Also, we are currently sticking with the free, open source versions of the programs but are willing to investigate enterprise versions.

Suggestions?

Thanks!
