The spyderco is probably the best all-around of the three, but id chose to give my business to KAI. They have the best warranty/CS in the business, and they will send you parts without question if you need them, spyderco will not, and they frown upon customers disassembling their own knives. that being said, i'd look at the link over the cryo. Lighter, and (at least with the aluminum version) the blade has a detent hole, so the knife can be de-assisted (i mostly hate assisted knives). Strange that i love kershaw yet hate assisted knives....lol, its a complicated relationship.
