It seems that the only distinction between dead and unconscious is made in the first couple of levels. And there is no real reason to need the GEP gun on the first level. Also, if you want to go non-lethal, then it might be wise to pick up the crossbow first. But if you spent skill points on small guns then you might want the crossbow right away, and the same with the rifles skill & the sniper rifle. You can loot the sniper rifle and mini-crossbow off of enemies in the first level so common sense would say the GEP gun.
