If you prioritize a higher resolution for detailed work or 4K media, the Asus monitor is the better choice despite its higher price. The Dell, on the other hand, offers a balance of good performance for both gaming and productivity at a lower cost, but with a lower resolution that may not be as suited for high-definition tasks. The Dell also provides a slightly smoother gaming experience with its higher refresh capabilities. If budget is a concern and you primarily game or work with no need for 4K, the Dell could be more economical while still meeting your needs. Give Feedback

"The Asus TUF Gaming VG28UQL1A is, in many ways, a great 4K gaming monitor. It has a sharp, accurate image with good contrast and excellent motion clarity. Luminance uniformity is its only weakness. The monitor’s $799 MSRP is relatively affordable for a 4K HDMI 2.1 monitor, as well."

"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."
