Buy the one that pleases you most. If you come down on the Cold Steel side of the tracks, go for it. Of my Cold Steels, they've all had excellent fit and finish and came with hair-popping edges. The Voyagers are affordable, have AUS-8A steel, lightweight - yet extremely tough - Zytel handles, and a choice of tip and serration configurations. Their combination of AUS-8A blade steel and serrations works very well.
I'd recommend one of their Vaquero series over their Voyager series because they look cooler and have flat grinds and large recurves.
There are several reasons to buy the AFCK, too. It's thin blade is one of those reasons (assuming you want to use the knife to cut). So is the axis lock, D2 steel, handle shape, G10 scales, Benchmade's outstanding customer service, and ambidextrous pocket clip with choice of tip-up or tip-down carry.
Glockman99 also mentioned Spyderco, which I also think are great. In fact, why not buy yourself a Delica or an Endura and forget about laying down near tracks?
