If you're focused on casual or competitive gaming and are sensitive to price, the LG 27GP83B would be a solid choice with fast response times and a high refresh rate, although it's less suitable for high-quality HDR gaming and media. On the other hand, if you're willing to invest more for a larger screen that excels in productivity, digital photo editing, and has better color accuracy for print photo editing, the ViewSonic XG321UG offers higher resolution and superior color performance but might not offer the same level of gaming responsiveness as the LG.
