If you're on a budget and primarily interested in casual gaming and digital photo editing, the AOC 24G2SPU is a solid choice that also has a good refresh rate for gaming. However, if you're willing to spend more for enhanced image clarity, better text quality, and a larger screen, the Dell S2721DGF offers higher resolution and color depth, making it better for media consumption and productivity tasks. The Dell is also suitable for more serious gaming due to its higher performance in response time and refresh rate. Keep in mind, though, neither monitor is ideal for HDR gaming or HDR video editing.

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."
