DarkRP FA:S vs M9K?

Im having a hard time finding out which gun swep servers use the most? FA:S or m9k? First of all is there a fix on how the weapon model moves when shooting? The FA:S contains better weapons overall, when aiming down on sights and shooting, the gun doesnt spazz out. Mean while m9k iron sight spazz out when shooting. Which weapon swep do you prefer and why?

FA:S 2.
