If you're looking for an immersive gaming and media experience with a large, ultrawide screen, the Acer Predator X45 could be worth the higher cost. Its wide aspect ratio and high contrast are great for HDR gaming. However, if you're on a tighter budget and primarily use your monitor for competitive gaming and productivity, with some digital photo editing on the side, the Acer X27U is more cost-effective. It offers high refresh rates and excellent color accuracy for gaming and content creation, although it has a smaller screen and may not be as well-suited for immersive media consumption.
