Modern 10 speed chains are all very close to the same 5.9mm width. From a width standpoint they are all interchangeable. I've only tried wipperman once, probably in 2001 and found the chain noisy. Never bought one again.
Your problem sounds like you need to adjust the cable tension on the RD, although RD alignment should be checked too. Hesitation on shifts to larger cogs means too little tension. Hesitation on shifts to smaller cogs can be due to inadequate tension or cable housing friction that keeps the cable from releasing properly.
You won't find any chain that lasts longer than Campy. I've been using Campy 10 since 2000. None of the chains I used ever showed much elongation, even after 6,000 miles. They do wear out, but you can't use elongation as the measure, if the chain is kept properly lubed. I measure roller wear, using calipers. When the spacing between the rollers increas by about .020 inch, the chain should be swapped for a new one, but not thrown away. I consider that to be half-worn. I alternate the use of three chains, so I never get chain skip.
