If you prioritize top-quality visuals and have a higher budget, the AOC monitor, with its OLED panel, offers superior contrast and color depth, making it better for HDR gaming and photo editing. However, if gaming performance, especially competitive gaming, is your focus and you want to save some money, the Asus monitor with its IPS panel provides a balance of good picture quality and high refresh rate for smoother gameplay, though it doesn't excel in HDR content as much as the AOC. The AOC's larger screen offers a more immersive experience but may be less sharp due to lower pixels per inch compared to the Asus. Give Feedback
