Your list is about as wrong as you can get. SUROS Regime is trash. You can get a legendary (purple) SUROS which has better fire rate, range, damage and stability and has superior upgrades. The Last Word is terrible. Thorn is superior in every single way. MIDA Multi-tool is a joke weapon. It deals almost no damage, has terrible stats and it's unique gimmick (finding chests) is so unreliable and poor it will actually increase the time it takes for you to find chests. Invective is one of the best shotguns in the game. Full auto shotgun with infinite ammo is amazing, especially in PVP.
