Sooooo... I'm going to give very different answers than most and if the steels I recommend when I started this I could have saved myself thousands of dollars getting to the place I am now... granted I probably wouldn't appreciate the knives I have now or how much better they are than anything I used to own.
More critical than steel is design, edge geometry, and heat treatment. Most commercial knives do not take them to the extent necessary to maximize performance. So its either custom maker, or regrind of commercial knives that have the heat treat done right.
EDC folder: This is going to get lots of use on things that dull soft, easy wearing steels, being dull often before the end of the day if you use it much at all..
so you want something really hard with amazing edge retention... For me that means Spyderco Farid K2 in 10V (Rc 65) with a Razor Edge regrind to thin the blade and drop the trailing point, OR a Benchmade 710 in M390 (Rc62) with a Razor Edge regrind to extremely thin the edge. Super slicer, but not super tough.
Camp/Woods/Survival knife: Tough, hard and great edge retention. You never know when you'll need it or when you might get a chance to sharpen it. So best have one that won't always need it. I choose CPM 3V in a substantial, but balanced design, not super thick, fairly thin edge Rc61 is a good place for this steel. Mine is a Big Chris SAR 6", tough, sharp, and holds an edge....
Skinning: See Phil Wilson customs for why you want super duper super steel done right. Better to have a tough, sharp, hard knife that you can skin 10 deer with before sharpening than one that needs to sharpened 3 times before you get through one... 10V, S110V, S90V, even M390 if done right, one of these....
Also you need a guided stone sharpening system with decent stones so you can do the regular maintenance on them. Doesn't take long even with these steels... My Spyderco K2 in 10 at Rc65 only took 2 passes each side with my DMT aligner and 600 grit DMT stone to refresh its edge after the regrind...with a couple months of regular hard work on it, still sliced paper, but not sharp enough, back to push cut newsprint and heavy plastic film.
