Agree to disagree. My Stihl chains last half as long as my Oregons. And cost 3 times as much. Course I only run rip chains and full chisel chains.
I do have a Stihl brand bench mount chain sharpener that’s about 35 years old or so, it’s pretty good.
Archer chains are pretty good too. They’re Australian made and I only have one but it seems to hold well.
I love Stihl saws, especially the older D series which are nearly indestructible but I’ve not had good luck with their chains
