The short answer from me would be that the only wheel on your list I've heard negative things about would be the Spinergy XaeroX; I've read about bad experiences with truing, spoke breakage, the fidelity of the hubs... standard alarmist talk. Take it with a grain of salt. It may mean nothing, but if you can find good deals on your other options, it may be worth passing the Spinergys over.
Campy wheels from top to bottom have hugely loyal followings; the Ksyrium Elites and the Cosmics are a touch heavy but generally regarded as rock solid. I'd also suggest you look into Velomax -- their Circuit Comp set is in the same price range and has garnered a lot of fans. The Shimano 540 wheelset is probably worth a look as well, along with the Ritchey Pro Z.
Lastly, don't forget to investigate built wheels. For as much or less cash, you can pair Mavic OpenPro, Velocity, or Ritchey rims with the quality hub of your choice (Chris King, American Classic, Shimano and Campy make some particularly popular and reliable choices).
The bottom line? Your choices are many. The differences can be quite subtle. Go with your gut, your sense of style, and follow the deals. Good luck!
