In general, all my Kershaws and every Spyderco except my Spyderflies win hands-down.
All my Protechs and Microtechs came very sharp, but just not quite as sharp as the Spyders or Kershaws.
My Benchmades are about 50/50 for "feeling" sharp, although all would shave armhair out of the box (for some reason though, some just don't "feel" sharp, or would tear/bind paper, even though it would shave).
But the single sharpest knife I've had purchased new was my humble Victorinox 4" paring kitchen knife (cost me like $5). Of course, it doesn't stay sharp as long as a ZDP-189 Spyderco, but at least it sharpens easily.
