Best pistol for me? MP - I’m on PS3, so I haven’t been able to grab my Hockler DLC yet, but the Bolgo is my favourite sidearm so far, and knowing the stats are identical, I’ll be enjoying the cooler appearance of the Hockler.
Best SMG for me? Galactic - no question. And I use it silenced, so I can’t support the “not enough power” argument either - the high clip was my main motivation for liking it pre-release, and with the way it handles when I’ve added a High Capacity Magazine, I can consistently take 3 - 4 enemies out without needing to reload - I can’t do that with any other gun in the game.
I won’t say any weapon is the best hands-down, or even the best in its class, though, because what works perfectly for me doesn’t necessarily suit other players. One of my friends uses the CARB-9 as his Medium Soldier’s backup weapon, and he’s great with it, but I find the Galactic works better for me.
