The Walker liner lock is just giving respect to the maker that invented it. Just like Spyderco calls it a Reeve Integral Lock instead of a frame lock. I have never seen a liner lock that did not use a ball detent as that would just be dangerous.
I would also like to know what is "gimmicky" about the AXIS lock? It is a great piece of engineering. It is strong, ambidextrous, will adjust for wear, both locks the knife open and holds the blade closed with the same spring pressure, and it keeps your fingers out of the blade path. I would say it just plain works with no gimmicks about it.
Spyderco may have some cheaper knives that provide a great value for what you get and Benchmade doesn't really have a counterpart to. But once you get to the $100 price point Benchmade is going to give you the same great steel with outstanding heat treat, the same great materials, and the same great build quality that Spydero gives you. Don't let that thought sway you as they both make great knives.
It always helps to know what you are going to use the knife for, how much you are looking to spend, and what size knife you like to carry or are limited to by law.
For Spyderco I would look at the stretch 2 (zdp steel if you can pull it), caly 3, or Manix 2.
Benchmade check out the 950, 14205, 710, and griptilian series.
