If you're looking for a high-quality gaming experience with vivid colors and deep blacks, especially for HDR gaming, the AOC PD49 with its larger, ultra-wide screen and superb color performance is an excellent choice, but it comes at a higher price. The Acer X27U offers a smaller screen with good color coverage, making it suitable for both gaming and digital photo editing, at a more affordable price point. However, due to its lower brightness and contrast compared to the AOC, it might not be as impressive for HDR content. If productivity is a priority, the Acer's smaller size could make it easier to manage on a typical desk, whereas the AOC's expansive display is better suited for multitasking but requires more space.
