My experience is the opposite and I like liner locks better. Once I was prying pretty hard on something with a Spyderco Endura serrated blade and the fleshy part of my had depressed the lockback bar and the blade closed on my fingers. Luckily it just pinched my index finger with the unsharpened part of the blade or I could have lost some fingers. Another little "life lesson" to not depend on any type of knife lock as total safety.
