I found force gun to be easily the best weapon in the game. Clearing impossible was a breeze with it. First use primary fire to knock down the enemy and then lob one or two grenades at them for quick kills.
Works great against groups as well and murders those swarm of annoying creatures which jump up on your back better than any other weapon.
