If you prioritize immersive HDR gaming and media consumption with deep blacks and vibrant colors, the Gigabyte CO49DQ with its larger screen and OLED technology will be very impressive. However, it's not as well-suited for productivity due to its large size and aspect ratio, which some might find overwhelming. On the other hand, the ViewSonic XG321UG, with a more traditional aspect ratio and smaller size, would be better for productivity and digital photo editing but may not provide the same level of immersion in gaming and media viewing. It's also worth noting that while the ViewSonic is more expensive, it offers a high peak brightness and more uniformity in brightness, which is beneficial for well-lit environments and consistent color work. Choose the Gigabyte if gaming and media are your focus and you're looking for a more budget-friendly option, or the ViewSonic for high-level photo editing and a more standard size for mixed-use.
