I prefer the A1-S, mainly because it stays on target after a few shots, and is very powerful at a free cs go skins(compered to A4, which loses damage at long distances). The main thing I love about it though(apart from the acuracy), is the fact that it doesn't fire tracer rounds. Have you seen gunfire pop through smoke, making it easy to identify where the enemy is by looking at the trajectory of the bullet? With the A1-S, that doesn't happen, making it effective for shooting through smoke(although that's not really that recommended due to the small ammo capacity). Also good for shooting people at medium distances because they won't be able to identify you as easily by sound thanks to the supressor. The A1-S is great.
