If gaming and media consumption are your top priorities, the Gigabyte with its larger screen and superior HDR capabilities provides an immersive experience, especially with its wide color gamut. However, it comes at a higher cost and may not be as suitable for productivity due to its super ultrawide aspect ratio, which can be more challenging for multitasking unless you prefer one large display instead of multiple monitors. The Asus, being more affordable, offers a good gaming experience and also performs well in productivity tasks due to its more conventional aspect ratio and size, making it easier to manage multiple windows. For digital photo editing, the Asus has great color accuracy, but if HDR video editing is important to you, the Gigabyte's capabilities might be worth the investment despite its higher price.
