Well, im the kind of guy who likes knives that are about 100 times stronger than they need to be, and despite Emerson's claim that theyre the #1 "Hard Use Knife", there is little doubt, once you compare the 2 knives, that the BS is the harder use knife.
As has been mentioned, for some reason Emerson uses very thin liners, and while i know and agree that liner thickess is but one factor in a lock, i cant help but think that generally, thicker is better and stronger. So, if thin liners bother you, youll greatly prefer the BS, if youre like me and you like knives that are extremely robust and heavy-duty oriented, again, the BS wins. As was mentioned, if you want a true monster folding knife, get the real Strider folders, as large and strong as the BS is, the real Strider AR/GB is doubly so and frankly an amazing feat of overengineering. If the AR/GB is simply too big for you, the SnG is of much more practical size and equally strong with its well designed frame lock.
