I am a huge fan of the crossbar lock, it's one of my favorites, and the silver lining for me is that many companies are using it, and have further refined it, making it better than Benchmade ever pulled off. Not bad at all!
That said, I do not mind liner locks, either. Companies have probably moved away from them because other locks "present" as being stronger than they are. Crossbar locks are more fidgity as well, and we all know that sells these days.
