I have not tried the porter cable version, but I have a few other tools by them and they are great feeling in the hands. I have tried about ten others since upgrading like you from air. Each seem to be all of quality. I do tend to buy more DeWalt sanding tools. I still remember the days of the auto body sanders and the compressor never stopping. Thanks for posting shin.
