Pros: Light and strong. Shifts a tad bit faster than my PC-971. Stronger too. The KMC missing link is actually reusable.

Cons: Pricy and pins are really hard to push out of it.

Recommendation: Great chain. But just a tad bit too pricey.

Pros: Light.
Shifts smoothly.
Compatible with Sram power link.

Cons: Price.

Recommendation: I just replaced my XTR chain with one of these and it performs the same, maybe slightly better.

Time will tell on longevity.

Pros: Great longevity and shifting

Cons: None

Recommendation: This chain has lasted me a long time so far and has seen me through all sorts of nasty conditions. The shifting is still great, and I've just been really pleased with this chain.

I have broken a couple of links, but I think that comes with the sport so that's no down fall. Totally compatible with SRAM powerlink technology.
