If you prioritize competitive gaming and have a higher budget, the Acer X27U with its superior response time and higher refresh rate will enhance your gaming experience. However, if you're looking for a more immersive experience with a wider screen for productivity and media consumption without spending as much, the Dell S3422DWG with its larger screen and good image clarity might be the better option. Keep in mind that the Acer's OLED panel offers better contrast and is suitable for HDR gaming, while the Dell's VA panel has its strengths in contrast ratio without HDR capabilities. Choose the Acer if you're focused on high-end gaming performance and the quality of HDR content; opt for the Dell for a wider screen and good all-around performance at a more accessible price point.

IGN
Whitson Gordon | August 2021
"The Dell S3422DWG is, overall, a great monitor that delivers on most of its promises, providing a sharp ultrawide experience with smooth motion. It is, however, not as great of a value proposition, costing a bit too much compared to similar competitors."
