There's something to be said for the survival by numbers. For the price of a single higher end of mid-range knife (let's say $100 - 150), I can buy 10 opinel 8's in stainless. Or a bunch of smaller and bigger ones in various steels. If I'm not edc-ing it, that would actually be a viable option, and probably preferable if I'd go camping, so when one knife gets potato all over it, I can still slice meat with another, and saw off a tree branch with even another.
More realistically though, there's really no possible way to point out a best knife. Different blade and handle shapes, sizes and steels / materials have different characteristics.
A light and slim knife that might be perfect to edc, could be your worst choice for actually using an hour long. The flat and open handles can dig into your skin and cause blisters, and the blade might be too small.
In opposite, a bigger and comfortable knife like a Buck Alpha Hunter 277 if useless to edc and weighs a ton.
A blade with a supersteel might be too hard to sharpen quickly in the field if that's something you might need to do.
All that said, there's a balance. Something between too small to use and too big to carry, too easily blunt and too hard to sharpen. For some reason I'd probably pick a Cold Steel Code 4 if I had to balance everything out and could only pick one knife, but I don't edc it because it's a bit on the large side. It is a very handsome knife though, and extremely rugged. Handle is not as comfortable as some others but holds amazingly well when wearing gloves (try this for all your knives by the way, for some it's a massive difference).
Like we say in photography: the best knife is the one you have with you (although we use "camera"). For that reason, ability to carry is always high on the list for me. What use is a knife if it's sitting in a drawer at home, except to occasionally fondle and admire it.
