Based on both reliability and ease of use, I'd vote for Spyderco. My Military is by far my favorite folder, regardless of lock types.
The Outdoor Edge Magna, while not as fast to deploy the blade and not as easy to disengage the liner lock, seems nearly impossible to accidentally disengage the lock, due to the barely-exposed liner and the very strong tension of the thick locking liner.
Of the knives I own, I'd pick the Military as the best overall design in the $100 price class and the Magna as the very best value in the $40 price class. The Magna outclasses any of the CRKT knives in terms of value, especially when you compare the AUS8 blade of the Magna against the AUS6 blades offered by CRKT in the $40 price class.
