If high-contrast, stunning visuals and top-notch response rates for fast-paced games are your priority, the more expensive Asus monitor, despite its higher cost, will deliver best-in-class gaming experiences and is suitable for HDR gaming and media consumption. It also offers the smoothest motion. However, if you're looking for a monitor that's more affordable and also offers excellent image clarity, high brightness for HDR content, and very good color accuracy for tasks like print photo editing, the CoolerMaster is a more cost-effective choice that still performs very well for a variety of uses including productivity and media consumption.
