I'll sound a little similar to s0nspark here. Since the early nineties I've owned close to fifty different pistols from all the big name manufacturers, along with renting countless others, and the P-07 Duty is by far one of my favorites. The XD9, XDm 9, and XDS 9 are all long gone, and for that matter, did not stay in my stable for long!
Concerning competition, the only striker fire handguns that I do carry or, would consider carrying as much as my P-07 are my CZ 100, the Glock 19, and Sig P320 C. But that's a whole other, different conversation for elsewhere. Back on point, when it comes to a hammer fired polymer handgun, the one that works best for me out of all the available options in the marketplace is the CZ.
