If you're a competitive gamer looking for high performance with a much higher refresh rate and quick response times, the Asus PG279QM would be the better choice despite its higher cost. However, if your focus is on casual gaming, everyday productivity, and you're mindful of your budget, the Dell S2721DS offers a good experience at a lower price point, though it won't match the Asus in terms of gaming performance. Neither monitor is ideally suited for high-end HDR gaming or professional color work, but the Asus provides better color accuracy for tasks such as digital photo editing. Give Feedback
