I've not used the PP6 but from what I've read it is a great tool but offers, dare I say, too much user interface. I'm running an Emanage blue and it is relatively idiot proof (that is after I figured out how to install it... I wrote the install instructions that are floating around the www). The PP6 (again, from what I've read/heard) strips away some of the safeguards that many of the entry level user tunables have to keep you from blowing things up. In that regard it is more capable and also more capable of being a major headache for the untrained/inexperienced. Correct me if I'm wrong.
