not to diss the Manix, but i'd say the military is the better choice.
most people planning to buy the Manix come up with the overbuilt-like-a-tank lock and its overall built and heft, but in my opinion the Mili has as strong as a lock and construction you'd ever need in a folder, plus it's a real featherweight. some people would also argue that the Manix might chop or pry better, because it seems stronger. suffice it to say that those are things you shouldn't do with any folder whatsoever, because all will fail at the pivoting-area and lock, even the Manix.
now you may think "but the military doesn't feel heavy-duty at all"; well, let me explain, the first time i handled a Mili, i thought the same thing of it: the thing looked and felt fragile, and "that tiny liner-lock" could never be strong enough......; but, boy how wrong i was! at first the knife may seem fragile, but once you start using one you find out that it is indeed very, very strong, both the lock and the built in general. i was and still am very impressed with the military.
also very important is the weight issue. with the Mili you won't even notice you're carrying it, it's that light, but the Manix is a total different story, realize that. it weighs something in between the weight of an AMK S2K and a Buck-Strider, and you definitely will feel it dragging your pants down.
so, think twice before you buy one, no matter how cool it looks, unless you don't mind walking around all day with over 6 oz. in your pocket
