Kershaw Vapors are nice. The Benchmade Vex is exactly the same in materials as the Tenacious, at the same price point. The ergos are about the only difference, which is a highly subjective and debatable point.
Lots of folks like the Tenacious for it's exposed hole on the wide blade - but I prefer the Vex with its slimmer profile in my pocket, because that's where it really needs to fit 95% of the time. The dropped butt on the Tenancious handles well and rotates the point down for cutting, but I use the Vex a lot with a finger near the tip in a choke hold, and a straighter grip helps me. Again, that dropped butt takes up more pocket room in carry, not with the Vex.
Needing to get into a pocket for other stuff has a priority, too. I don't need to fight my way past a wide bladed, curved handled folder that inhibits the process, especially in jeans.
Knives are more than just about themselves, but how they fit into your overall use.
