In general IMO....
Fixed blade cpm3v...cpm m4...l6...just to name a few..
Folders Zdp-189...cpm s90v...m390.....just to name a few..
There are many other options and variations...depending on what your cutting ect...
I agree in general there's no "best steel" for everything. This isn't a bad list of "leading steel options" though.
Of course, I'd want to throw in some of the nice carbon steels: 1095, 5160, SR101. Hard to beat for toughness.
