Most ranges kills were 2 tap headshots or a headshot and body spam. Since this has not changed I think CZ is still the better of the 2 weapons given the run and gun and close range. high ROF body spam.
57 has fucking terrible accuracy ! medium range is a joke lol i decided to use it once awhile ago and was at balloons overpass crouched aiming perfect HS on a still target who was against the far wall with hedge on toilet side and the bullet went half a metre to the left its a literal joke ! RNG to the max
