If you are a serious gamer looking for an immersive experience and premium image quality, the Asus PG49WCD (QD-OLED) with its wider screen and excellent contrast and color could be a great choice, but it comes at a premium price and might not be as suitable for productivity due to its size and aspect ratio. On the other hand, the Dell S2721DGF (IPS) offers good performance for gaming and productivity tasks at a midrange price, with a more traditional size and aspect ratio that's better suited for general use, although it doesn't match the Asus in image quality or viewing area.

Tom's Hardware
Christian Eberle | January 2021
"The Dell S2721DGF checks all the boxes for an upper-mid priced display that can take on the best gaming monitors, and you might even be able to find it for under $500 (it's $450-$500 as of writing). The monitor's 1440p, runs at 165 Hz without overclock, has AMD FreeSync Premium Pro and G-Sync Compatibility, covers a large portion of the DCI-P3 color gamut and includes a lighting effect on the back."
