2000 hours, I played with every of it.
S+ has guns which most of the people should have ready to play with, Annoying are the ones which tubers or guys with shield+C4 play, Trash are the ones which are rare to be used to achieve something. Some of my choices can controversional, I depend on the recoil, ammo and dmg the gun deal.
