Depends on what you looking for in a knife and what your intended uses are. Though I may get flamed for saying this here, many knives, and varied price points are capable of performing tasks in a very similar fashion - think cutting food, rope, cardboard, opening shipping boxes containing new knives ... you know, the regular EDC stuff we use knives for.
Some steels hold and edge longer and require less frequent touching up. Some are more corrosion resistant than others (H1 versus 1095) while some are more forgiving of abuse and less prone to chipping. Some are tough to sharpen with normal stones or ceramics.
Then, there is the whole fit, finish and pride of ownership thing. My FRN handle Cold Steel Voyagers provide great function based value but pocket jewelry they are not. The more knives I have used, owned and evaluated - the more I realize that after a certain point, additional cost is not linear with additional performance, reliability, function or durability.
I'm sorry if I failed to make specific recommendations to you but my (folder) users have settled on Cold Steel, Emerson, Spyderco, ZT and Benchmade - the latter being crossed off my list ... not because of anything wrong with the knives, but because of the company. In that vein, there are other knives that are seemingly fine as a product, but, being a personal item as they are (especially to us here at BF) I just cannot support certain companies. Benchmade just got added to that thankfully short list.
