I don't worship any manufacturer, and when the HK USP series came out in 1994, I was not super impressed. It seemed like HK had realized that the only way that they could compete with other manufacturers was to injection mold 1/2 the pistol.
I eventually wound up with a USP.45C
Reasons:
1) Supposed to be very corrosion resistant
2) supposed to have fewer problems with case rupture than Glock. Rated for +P
3) the HK Compact fits my hand very well
4) polygonal rifling for the tech weenies
5) Very good reputation for durability and reliability
6) tactical light can be hung off rails, although tactical light costs more than it should
7) I like the exposed hammer over a striker.
8) reasonable weight.
Ultimately, it all depends on whether the HK feels right to you. If it does, I think you will be very happy. If it doesn't, there are plenty of other excellent pistols out there.
