Been running the KMC gold 9 on my Marin for 6 months now. Wear at 50%. Ate 2 SRAMS in the same period last winter
The KMC shifts better, looks better, lasts longer and its quick links are easier to use than SRAMS. I wont be downgrading to SRAM again in a hurry
Remember KMC actually make many of Shimano's chains for them
