I doubt its any more durable. The substrate is soft, and that is how you get scratches. The anodize is harder than cerakote. Also type iii class i anodize is the only way to properly "clone" the real guns.
Not true, several bronze color HK416 guns that are that darker shade are Cerakoted not anodized. Also the latest ral8000 csass that was displayed was Cerakoted.
Watch this video vs durakote, which isn't as durable as cerakote. https://youtu.be/hhwdGaxA-mU
