If you prioritize competitive gaming and want the best visual experience with deep blacks and a high refresh rate, the Acer X27U (W-OLED) is a better choice, despite its high price. However, if you need a monitor better suited for productivity with higher resolution and are on a tighter budget, the Dell U2723QE (IPS Black) would be a more cost-effective option, though it's not ideal for high-frame-rate gaming or the best HDR experience. Both are suitable for casual gaming and media consumption, but the Acer excels in gaming performance while the Dell offers more screen real estate and sharper text for professional tasks.
