I've seen good reports for it. Here Here But, I'm still impressed with mine. I have about 3000 miles more road than gravel, and using muc-off C2 and C3. Less than 0.5mm stretch. Expensive, but seems pretty solid.
I don't have any experience with the SRAM chain, but have been using YBN SL1 with wax and have really been impressed too. Much of longevity has to do with just keeping up on the maintenance.
