I have heard a LOT of positives about the PC but have not used it. I love my Kreg, it suits me just fine and for the money out it was a no brainier at the time. And I'd agree with Rich that the K5 is definitely the cats meow of the different types of Kregs out there. I have the K4, I don't use it all the time but it's a great jig and in an effort to offer myself the benefits of the K5 I added a base with extensions to support material. I made mine out of OSB, sanded the edges and it works pretty well. If I were buying one for the first time the K4 is generally $99 and the K5 is $139, I'd probably spend the extra and go with the K5, mostly for the support and I have had mine for years so it doesn't have the DC hood which you really should have as the chips get in the way.
