I carry, use, and sharpen an Al-Mar, 4 D4s, and 4 Grips/mini-Grips in VG-10, D2, ZDP-189, and S30V. All of mine will slice and push cut newsprint, shave hair, and do actual useful cutting, one about as well as the other. I have found that Spyderco's OOB sharpness is consistently the best I've ever encountered on factory knives in 50+ years of buying knives. My Benchmades have not come as sharp as my Spydercos, but they have all touched up quite nicely.
I use the same equipment, sharpening techniques, and tests on all of them. Oops... I tell a lie... I reprofiled two of my D4s on my EdgePro. The back bevel is set at about 12 degrees and then I touch them up on my Sharpmaker and strop them a couple of times on an old leather belt. The others just get touched up on the Sharpmaker at 15 degrees (fine and U/fine rods) before they get dull and they're always ready to go.
