AEB-L
It's available, it's affordable, it's easy to work. It's extremely tough and can be ground super thin with great stability. That means it will cut well even when the edge is dull. It's stainless enough for my neck of the swamp. Because I like high sharpness in my knives, and am happy to sharpen and hone periodically, AEB-L is a clear winner for me.

It is everything I love about AEB-L with a few adjustments. It is not quite as tough on paper, but it's still more than tough enough. So no lost points there. It takes almost as sharp an edge, but not quite. However, it holds working sharpness better somehow, and though it is not supposed to be as tough as AEB-L, I always find in practice it seems more so, if not at least on par. Edges never break, they roll, and even with all kinds of light deflecting off the apex, it still cuts aggressively. I love it. It is a winner.
Both of these steels can do, in my opinion, anything. Choppers, small knives, kitchen cutlery, you name it.
I don't know of another steel that even comes close for me. I love 15N20. I love 1084. But the lack of stainlessness, though not a problem per se, is not what I would make for myself in most knives, except maybe kitchen cutlery. I am doing a run of MagnaCut soon, and perhaps it will make the list. I am betting it will.
