All my Spyderco knives are from Colorado (Paramilitary 2's, Para 3, Native 5). I have zero complaints about the factory edges. As far as I have been lead to believe, they're all robo-sharpened (correct me if I'm wrong).
In regards to Benchmade, I find the edges on the knives I have are more than acceptable considering they're all sharpened by hand. I've never had one with a burnt edge or a lopsided grind.
Zero complaints here as well. My pm 2 in s110v still has its very sharp factory edge.
