Data-no. Experience,yes. I bought the speed form from kershaw guy and a delica in ZDP from knifecenter because of the supposed super steels. I also have a zt0300 and a CRK sebenza 21 in s30v. All of them I have had to sharpen twice as much as my recon 1. The only folder that has better edge retention is my SOG Vulcan in Vg-10. I use them all equally. I think some of those other steels are too hard and brittle for horizontal forces. Edge geometry, thickness, steel comp. and cutting action all have a lot to do with it. I'm not talking about just cutting hemp rope over and over with the same cutting motion, but real world use, in whatever may come.
Interesting. I find the opposite to be true in my own usage. I've used AUS8A from CS, S30V from both Spyderco and Kershaw, and ZDP-189 from Spyderco, along with a few other steels. I cut a lot of cardboard at work, and found that ZDP held an edge longer than S30V and AUS8, in my own experience. CATRA tests come to similar conclusions. But hey, if it works for you, by all means use it.
