In deathmatch you can pick any weapon and spawn with it every round. In Comp, you fight for your money. The AK is $2700. The AWP is $4750. So in comp, people typically run around with AKs. People that are good with them will even switch to them from M4A1-S as they are guaranteed 1 shot headshot kills.You know, it's not like all terrorists in death matches are running around with the AK. Is it more popular in Competitive? All I've seen is the large number of players who all think they're amazing at using the AWP, and somebody's always complaining about "Oh, it looks like a joined an AWP server" on voice chat.
