I have more than a dozen semiautos and revolvers, and can afford any gun that I want. I like each of my pistols for various reasons, but I carry my PX4 Compact 75% of the time. You can pay more for any number of pistols, but in my opinion, they won't be any more carriable, shootable, accurate, reliable, or handsome than your PX4.
If you like the features and it feels good in your hand, it will make an excellent gun, whether it is your only one, or one of many.
