I'd say the MSMC yes, the PDW is hit or miss for people.
I'd say the 'top' guns in the game are the MSMC, AN-94, FAL, TFLMG, and maybe the Type-25 after the most recent patch.
How noticeable is the movement speed buff for the Type 25? Did they basically turn it into a jumbo SMG?
I believe a normal AR has a 95% movement speed, an SMG has 100% movement speed, and the Type-25 has a 96.5-97% movement speed. It's noticeable, not really that impressive, but definitely noticeable and helps out.
Yeah the AN-94 is my current favorite. But they really are all stellar except for the M27, it's a dial-up gun in DSL world.
The M27 is good. Really good. The lack of recoil makes it amazing at ranges and laser makes is decent at close range. Not a single problem with it, and it's my favorite weapon alongside the AN-94 and SVU.
