The liner lock is not my favorite by a long stretch, but a lot of my favorite knives use it, mostly Kershaws. My favorite lock has to be the Benchmade Axis lock, for smoothness and ease of operation, one-handed opening and closing, and positive, solid location of he blade. It works so well that the assist feature on some BMs is hardly necessary. (That won't prevent me from buying assisted Benchmades, however, when I can afford them.)
