PC is 3.7 amps 2500-6000 opm, DeWalt is 4.3 amps 4300-6800 opm (I don't know how throw of their orbits compares). Considering I didn't hear of anyone using PC at speed setting of 3 or less I would guess one can say DeWalt covers same working range as PC and bit more, but that bit extra might not matter to 95% of the users. Big difference might be coming in user friendliness area as DeWalt keeps talking about how theirs is low vibration / low impact on user.
In other words, you are having tool that seems will do just fine, and market's PC mantra might be just that, a mantra. I personally am having PC because, well, that's what I kept hearing about.
