I haven't seen too many Campag wheelsets so can't comment on those, but would happily reccomend Mavic Ksyrium SL or Equipe having seen so few problems on so many wheels, or Bontrager X-Lite having done a lot of miles on a pair. You'll have to go to the ***-Lite to get a tubular though. A colleague chose these for the last couple of seasons racing.
Maybe controversially, I'd suggest bucking the trend and getting a pair of hand built traditional wheels built. For what I feel is a small performance gain (if any) the reliability and ease of repair of a bunch of easily available spokes is tough to beat. The choice of number, gauge and style of spoke makes tuning a wheel to your riding style much easier. The prices work out really well too.
Campy hubs are sweet running, well built, reliable, rebuildable and of course sexy. Mavic rims seem to win on reliability, but don't have a choice of tubular rim (choose the Reflex or the Reflex). With clinchers though you have an aero option with the CXP33 or stick with the classic Open Pro
If you break 1 of 32 spokes on a long training ride you can ride home pretty normally as your wheel should stay pretty true. Break 1 of 16 and you should be getting nervous.
