The SS is held together by flush pins, the G-10 by screws. The SS is going to be heavier and slicker, so it will feel different in your hand. possibly very different. The SS Dfly's clip allows RH/TU carry only, the G-10's can be mounted for RH or LH tip up carry. All of those things will be trivial to some but one or more of them will be critical to others. Beyond them, and the points already mentioned, there's probably not much.
