If competitive gaming is your primary focus and you're looking for a larger screen with higher refresh rates, the AOC AG456UCZD (W-OLED) is the better choice, offering a more immersive and responsive gaming experience at a lower price. However, if your priority is digital photo editing, HDR video editing, or print photo editing with a sharper image and more accurate color reproduction, the Asus PA27DCE (W-OLED), with its smaller but higher-resolution screen, is a more suitable option, despite the higher cost. Both monitors have excellent color depth and contrast due to their OLED technology, but trade-offs include the AOC's weaker text clarity and image clarity for productivity tasks, whereas the Asus performs poorly for competitive gaming scenarios due to a lower refresh rate.
