Sniper rifle: Kishook Why? well it reloads about twice as fast as any other high power rifle, penetrates guardian shields, gives a nice momentum effect when it kills.

Shotgun: venom (although I clicked on GPS first). Too broken.

SMG: Hornet. Its light and you can pull out a nice rate of fire while its still controlled.

Pistol: N7 eagle probably.

Assault rifle. Argus. Tough one but the Harrier burns its ammo too fast, Typhoon is too heavy. The Argus when specced for stability can rip through enemy infantry but starting the burst just below the head.
