Last week I interviewed the product manager of Puppet [0] and asked him to differentiate Puppet from Chef and cfengine. He didn't fall for it, and just said something like "the most important part is that you do something."

I've used both (and cfengine) to varying degrees and would have to agree. Simply using a configuration management tool takes an incredible amount of work off your shoulders, you can't go wrong with either.
