Other weapons - Main Rifles (M4/AK) are as good as the AWP. Both AWP and main rifles have advantages and disadvantages and have strengths and weaknesses in different situations .
Of course at a lower Level of Skill (low-Mid) playing against similar skill level players, might give you a lot of Advantage using the awp, at higher skill level this is not the case.
But the reality is that in CS (public servers) it's better to practice your AWP skills and ignore people complaining, then using other weapons and getting accused and banned for cheating.
note: People use the awp because once you are good with it you are unstoppable, and after all you are trying to win, but apparently that makes you a noob.
