I've used several brands with DLC coated blades... Benchmade, Protech, as well as Spyderco. DLC is extremely durable. I carried a DLC-coated TR-3 SWAT every day for a couple of years of warehouse work and home daily use. The blade still looked pretty clean and well coated when I sold it. Even my old garage beater original Paramilitary is not as scratched up as you might expect it to be for a garden/garage/whatever knife.
That being said, I don't prefer coated blades unless it's a steel that would benefit from extra corrosion protection. So Cerakote is more useful to me than DLC. I do have a couple of blacked out Bugouts, though, and I certainly like them. It's about the lightest daily carry folder I've ever had and if I have to have DLC to get that version, it's worth the cost to me.
