I like the 5" Springfield XD, but for me, it's the SIG X-5. It fits my hand beautifully and just plain appeals to me. Although if HK gave the P30L a nice, smooth, light trigger, I'd go with it.
Point is, you must get what works for you. All the ones you listed are very good pistols. It all comes down to what fits your hand and just plain works for you.
