It's a win-win decision, it unlikely you will be unhappy with either one.
I have a P-01 that is my EDC. I personally liked the visual balance better on the P-01, but I'm certain that if I started with the PCR I would be equally as happy. The PCR is a little slimmer in the nose as it doesn't have a rail, but I have no trouble concealing my P-01 and wanted the option for a rail. A good holster/belt combo will matter more for concealment than the difference between rail or not...
