If HDR gaming and media consumption are important to you, both monitors perform well, but the Cooler Master has a higher brightness which may offer a slight edge in visual impact. For color-critical work like digital photo and print editing, the Cooler Master also has a slight advantage with better coverage in certain color spaces, making it more suitable if you intend to work with a wide range of colors. However, both monitors have fast response times and similar high refresh rates, making them great for competitive gaming. Choose the AOC if you value the absolute best in contrast and response times; opt for the Cooler Master if higher brightness and color accuracy align with your needs for gaming, media, and content creation.
