puppet

I'm curious which tool is generally preferred for infrastructure management: Puppet or Chef?

Here's a rough unofficial analysis of high level points.

Puppet

• Older product
• Stronger community than Chef
• Significant number of community modules https://github.com/search?q=puppet (1947) at current count http://forge.puppetlabs.com/
• Written in Ruby but requires a Ruby DSL to really use the language.

Chef

• Newer product
• Less community support and activity.
