Chain tests performed in laboratory conditions on test rigs are meaningless to the consumer. They are strictly for manufacturer clout. I've used chains from pretty much every major brand, and lubes ranging from plain wax to almost-perfume-expensive MucOff Hydrodynamic.

...and you know what? Of chains of the same speed (and therefore plate width,) no chain lasts significantly longer than any other. The variance is within 10%, and could be narrowed down to riding conditions as much as anything else. The lube doesn't matter, the brand/cost of the chain doesn't matter.

So I buy the cheapest chains I can find (like the usually lambasted SRAM PC-1110) and wax them (for cleanliness above all else) and they last 3,000-3,300 miles... just like every other brand/make/model. Some might shift a little better out of the box, some might run a little quieter on a particular cassette.

But once you peel back the bling of coatings or "special technologies," a chain is a chain is a chain. They're built the same way to do the same thing. Buy the chain you like. Buy it if it's coated and you like that. But don't expect miracles.

For point of reference, I had a Wipperman 10SB followed immediately by a KMC 10.93 last almost the exact same amount of miles, on the same bike, using the same lubrication. But that 10SB was one sexy chain.
