If you prioritize high refresh rates and superior response times for fast-paced competitive gaming, the AOC AG276QZD would better suit your needs, but its smaller screen and lower resolution might limit productivity and media consumption experiences. On the other hand, the Dell U3223QE offers a larger screen and higher resolution which is great for productivity and detailed media consumption, but its lower refresh rate and response time may not satisfy demanding gamers. If you're looking for better color accuracy for tasks such as photo editing, both monitors provide good performance. Choose the AOC for gaming performance or the Dell for productivity and 4K media.
