This "Vs" has been all around the CS2D. But honestly.. Which is actually better? I have my answer. But you'll decide too.
M3 Description: is a shotgun. it has the power for a one hit kill if you aim right. There's a short pause after a shot. M3ers can get owned very hard with any assault rifle.
AWP Description: is a sniper. One shot with full scope on will lead to a kill. There is a very long pause after one shot. Though, It's dangerous if your enemy is good at the AWP.
