I prefer good carbon steel but have learned the last 10 years that stainless if taken care of will hold an edge longer. It will take a little more work to keep that edge in good operating condition. But not that much more.
As to the particular knife you mentioned, it fails on a couple of points for me.
A I admit that I am a knife and gun ***** but I am a cheap one. Yours is about double what I would ever spend.
B Pocket clip is on the wrong end. Should be on the other end. So when you slide it out your finger falls naturally on the flipper to open it. The way it is at some point you have to give the knife a 180 degree flip to orrient itself to your hand correctly. Which is a point where Murphy can step in and cause a bobble.
Just at the point when you need it in your hand, open, ready for business.
C IMO the blade is a touch short. I'd of been happier with a 3.25 to 3.5 inch blade.
D As to steel, only way you know that for sure is time and experience.

Bought my first 2 from BudK for 20$.
The Damascus black takes and holds and edge well.
I see with this one they got the pocket clip fixed. So ordered one to test it out. If it makes the grade its my new EDC.
