If you prioritize competitive gaming with a high refresh rate and low response time, the Asus monitor is a solid choice, offering crisp motion and support for variable refresh rates to reduce screen tearing. However, if you lean towards immersive HDR gaming and media with vibrant colors and deep blacks, the MSI with its OLED technology will deliver superior image quality and a much wider screen for an enveloping experience. For productivity and multitasking, the larger, ultra-wide MSI might be advantageous, but the Asus with its higher pixels-per-inch could offer better text clarity. The Asus is also well-suited for digital and print photo editing with a good color gamut range. Give Feedback
