If competitive gaming is your priority and you don't mind spending extra, the Asus monitor is a better choice as it offers a higher refresh rate and lower response time, which translates into smoother gameplay and less motion blur. However, for tasks like digital photo editing, the Dell monitor might be a better fit as it provides higher screen resolution, resulting in sharper image details, and it's more affordable. Neither monitor is ideal for HDR gaming or media consumption due to limited HDR peak brightness, but if casual gaming, productivity, and everyday media consumption are your uses, the Dell delivers good performance for its price.

How the Asus PG279QM (IPS) and the Dell S2721QS (IPS) compare to other monitors

"The Dell S2721QS 4K monitor brings IPS-level colors and some handy features, like a versatile stand with height adjustments and picture-in-picture for connecting dual systems. But don’t get it for HDR."
