If you prioritize a larger screen for immersive gaming and media, the AOC AG456UCZD with its greater size might be appealing despite its higher price, but for a well-balanced monitor that offers high image clarity and HDR performance for both gaming and media at a lower cost, the Dell Alienware AW3423DW could serve you better. The Dell's better peak brightness in HDR also ensures that HDR content will pop more. For high-speed gaming, AOC's higher refresh rate is advantageous, whereas Dell offers a glossy finish that can enhance color vibrancy but might reflect more in a bright room. If you're into competitive gaming, the faster response time on the AOC might be the deciding factor. However, if productivity is key, the Dell's better text clarity might tip the scales in its favor.
