Militaristic as a use case, industrial as a design methodology. It's the only system I'm aware of that has a ballistic justification for both damage and armor (at least in 4E, for non-medieval weaponry).

I myself like GURPS a lot. The point buy nature isn't even the major factor here, but the "physics engine" stuff. A satisfying resolution mechanism where quite often when I ask "What's the equivalent for this real-world action" you got someting that slots in nicely. And a 3d6 bell-curve hits my sweet spot.
