The good ol’ Covie Carbine.

I think the Boltshot.
You forgot the pistols and the SAW might belong to Light Heavy 
And you might want to add the Concussion Rifle and Scattergun
Anyway here are my favs:
Rifle (mid range)
Carbine
Sniper Weapon
Beam Rifle

Sword or Scattergun

Tough choice between the Railgun and Needler… The concussion rifle seems to be really powerful too. But I think I’ll have to go with the needler
Automatic
Storm Rifle
Big Heavy
Incinneration Cannon

Favourite pistol is probably going to be the Plasma Pistol since it’s been an all time favourite weapon, but the Boltshot is going to be close.
DMR
Beam Rifle
Shotgun
Railgun
Saw(even though it’s a power assault rifle is my favorite non-power weapon machine gun)
Rocket lawn chair of course!
