If you're looking for a monitor that provides a great gaming experience with a wide field of view and are okay with a lower resolution and smaller size, the Acer X34V could be a great choice at a lower price. However, it has limited brightness, which may affect HDR gaming and media consumption. On the other hand, the MSI MAG 321UPX offers higher resolution and size, which is better for detailed work and watching media, with higher brightness that enhances HDR content. It costs more, but for those who value sharper images and more screen real estate, it could be worth the investment. Both monitors are excellent for color-critical work like photo editing due to their color accuracy and depth. For competitive gaming, the MSI has a slight edge due to its higher refresh rate.
