It all makes sense now.

Turtles are my favorite, but there definitely don't hold an edge.
As for the rest, to each steel it's purpose.
In my general hunting knives, I want stainless, and I want edge retention. It is amazing how fast deer tallow can dull a knife and the last thing I want to do is resharpen mid-way through a cleaning or skinning. Also don't want to carry sharpening gear into the field.
In my caping knives, I want the finest sharpest edge I can get along with edge retention so I usually favor non-stainless there.
For the rest of it, I am not so particular. Super steels are more of an intellectual curiosity for me than a requirement. I enjoy learning about them and what they can bring to the party. Good to have that knowledge to tailor the steel to a specific knife / task. But until I get a high end sharpening system like wicked edge, I've found I spend far too much time trying to resharpen the suckers once they loose their factory edge. Worse yet if the knife arrived with a sub-standard edge from the maker.
If I have learned nothing else from BF, it is that steel is just one circle in a very complex moving target. On paper 420 is an lower grade of knife steel compared to 440C. Yet Buck's heat treat allows 420 to beat out many makers using 440C. So Steel is only step one. Add heat treating, edge geometry, overall grind and design, knife design and purpose... One maker's S30V outperforms another makers S35V for one knife design, but not another.
And all of that is before someone reaches their own conclusions about specific steels that may have little or nothing to do with the actual facts and characteristics of the steel. We all are subject to basing opinions on factors and beliefs that may not even be facts.
