For me (5'10", 165 lbs., carry AIWB), 5.0" height is the Goldilocks Zone for shootability/capacity and concealability. This pretty much means the G19, P2000/USP Compact, and M&P 2.0. I carried a P2000 for a while and still have one around that lives in a hidden compartment in a backpack. Boring reliability, and, while it's flippy, less bouncy than the USPc, probably due to the lighter slide.
I'm one of the genetic freaks that can't handle extended paddles in my HKs. I had a P30 for a second, but kept activating the mag release under recoil and dropping mags.
I've also tried the P2000SK multiple times, and found that the size difference isn't worth it vs. the regular P2000. To notice a significant difference, I need to go to G26 size (4.2ish vs. 4.6ish for the P2000SK/M&P "sub-compact" guns).
I think it's a great "do everything" gun and would be a strong contender if I was limited to a single gun. It would probably be the winner if I was limited to a single gun and had to trust it out of the box, sight unseen.
Mag release issues aside, the height difference alone would be enough for me to choose the P2000 over the P30.
