Which is the better chain for Campy 10s... Wippermann or KMC?

[Nags&Ducs]

I've read some of the past threads regarding these chains, but most posts have focused on the re-usability of the chain links. The consensus seems that for 10s, re-using the quick link isn't an issue for either chainset. I've used both before, but honestly couldn't tell if one was better than the other. The one thing I do recall was that the KMC chain had a propensity to develop surface rust. The rust was easily removed by running it through a chain cleaner. Since my experience didn't tell me which was better, looking for other's experience on these two. TIA.
