Why some people are so stupid.. the better gun is the one taht you are better with... Me i **** all of the ACR and Scar-L users with my M4 and P90 lol.. Why? cause they are good for me they work for my play stile..
IMHO -It really depends on what the other team is running with and the amount of lag in the game. ACR fires quicker and has a bigger clip (good for lag comp). SCAR does more damage but longer reload time and less ammo (not as good for lag).
