It truly is flip a quarter scenario. I currently own both and love them equally. I prefer the fit of the VP9 more, but the P10c has great texture on the grip. The P10c trigger is crisper and a shorter pull and reset. Accuracy is negligible. Both have been 100% reliable. I've owned multiple HKs and the paddle release is comfortable for me to use. The P10c's mag release was exceptionally stiff out of the box, but has smoothed out over time. Aftermarket support has grown for both guns and will continue to be more readily available with time.
