I prefer with a silencer, because I prefer being able to hear what my teammates are saying in vent and ingame. The M4 is a loud ass gun, and I usually have my volume cranked up.
I don't mind if it's weaker, I always hit the head anyway. Still does 112 damage, more than enough to get the job done.
I don't use silencer with tactical advantage in mind usually, I don't mind if the enemy knows I'm there, gives thema chance at least.
