I am not trying to be a smartass, but this is all just anecdotal evidence. If you don't hit the same object with the same force with same edge angle on different steels, it is just a one person experience, but not facts.
From Larrin toughness testing, LC200N and AEB-L are above everything stainless what Spyderco uses.
And then, steel is only a part of equation, very important is edge angle. You can have ZDP with some obtuse angle that is not going to chip, but AEB-L with some really low angle with chips.
EDIT: I can count on my one hand how many times I chip a knife. One in S30V Chief, I hit a spine on my Opinel. One chip with K390 on Police, I hit a big stample in cardboard.
I am not counting broken points, those are just thing that will happen.
In the pocket: Chaparral FRN, Native Chief, Police 4 K390, Pacific Salt SE, Manix 2 G10 REX45
