If you prioritize competitive gaming with a high refresh rate and responsiveness, the Dell Alienware AW2721D is an excellent choice but at a premium price. However, it's not the best option for HDR gaming and media consumption. On the other hand, the Dell S2721QS offers a higher screen resolution, better suited for productivity tasks and digital photo editing, at a more affordable price. It's not ideal for gaming due to a lower refresh rate and response time. Choose the Alienware for gaming performance or the S2721QS for a balance between work and casual use while saving money.

"If cost isn't an issue and you want a gaming monitor that will give your content all-new life for years to come, the Alienware 27 Gaming Monitor defines the upper echelon of what gaming monitors do best today. This display does everything the HP Omen X 27 tried to do, but does it a whole lot better for just a slight bump in price. If you're choosing between the two, the Alienware is the clear winner, and that story repeats itself again and again no matter which 1440p contender we put the Alienware 27 up against."

"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."
