Hello, right now I am stuck between three monitors, the Asus pg258q, xg248q (latest release) and finally the Alienware aw2518h. I am curious to know if g-sync compatible free-sync on the xg248q has the same quality and reliability as g-sync on the other two moniutors. In addition I don't really care about aesthetics, I am just looking for a monitor that has the best performance for competitive gaming. Finally, I heard that the xg248q has bad picture quality, if anyone can clarify on that subject it would be greatly appreciated. thank you for your help!!
