If you prioritize a monitor with a higher peak brightness and better coverage of professional color spaces such as AdobeRGB, which are crucial for tasks like print photo editing, the Gigabyte CO49DQ could be the better choice for you, despite its higher price. However, if you prefer a monitor with an adjustable stand for better ergonomics and also one that costs a bit less, then the MSI MPG 491CQP would suit your needs more. Both monitors offer excellent HDR gaming experiences and an immersive media consumption experience with their large, high-resolution OLED screens, although they aren't the best choice for competitive gaming due to their relatively high response times and potential for ghosting.
