I also have and like both. The P-01 is proven reliable and I trust it. The P10C has a way to go before I trust it. I also have 250 rounds through mine. No malfunctions so far, but it's barely come out of the case.
No one has asked yet how you will be carrying. If AIWB, the P-01 offers the advantage of being able to ride the hammer as you holster. I'm in the habit of doing this regardless of carry position.
I have CGW parts in the P-01. I try to go easy on modifying my self defense weapons. Basically, I just smoothed out the DA...some modest lightening of the DA/SA pull came with that. Do you need, CGW magic? Maybe not, but i wouldn't go back to stock. You might want to factor that into the cost. Rubberized grips are going to grab your shirt and make you feel like you're printing more. Factor in the cost of grips. The stock sights are...not... great. Factor in the cost of new sights.
I added the HB Industries trigger to my P10C. Generally, I'd shy away from doing so until the pistol is broken in, but I had some ergonomic problems with the stock trigger. The mechanics of the trigger we're great, but the dingus and the shape of the trigger would give me a pretty unpleasant blister after 50 rounds or so. I think I was getting pinched by the trigger/dingus and trigger guard under recoil. The HBI trigger has fixed that so far. The stock sights need an upgrade, so when the aftermarket catches up I'll be in line for some. But that's all it really NEEDS to be a good fighting gun.
The grip texture on the P10C is aggressive, but I like that. For longer range sessions, you may want talon grips or similar, but you'll probably get used to it pretty quickly. If you find the grip texture too aggressive then you'll probably feel the same way about the P-01 slide serrations.
I took a class with my P-01 and with all the drills the constant decocking tore up my thumb pretty good. You don't want to train only SA, so it was good practice, but now if I'm going to do more than a few dozen drills I tape up my thumb. Some people will claim that a TDA is not ideal because to difference in trigger pull. But lesser men have mastered it so there is no excuse for me not to.
The P10C feels like a more modern gun because it is. The weight isn't much different, but something about the P10C seems lighter and more concealable on my belt. That's entirely subjective and YMMV. The cost of ownership may end up being higher on the P-01 as I don't feel like the P10C needs much to work as a fighting gun. But either would serve you well assuming the new guy proves reliable. And that's the big thing...the P10C has a lot going for it, but I have some trust issues and it needs to prove itself before I carry it.
