If you prioritize a top-tier gaming experience with fast response times and high refresh rates, the AOC AG456UCZD is a premium choice, offering excellent performance for both casual and competitive gaming, but its text clarity and productivity performance aren't as strong. Conversely, if you're looking for a monitor that provides a good balance for productivity, media consumption, and casual gaming at a more affordable price, the Dell S3221QS strikes a better balance. It offers higher screen resolution for sharper images, but has lower performance in high-speed gaming due to its slower response time and refresh rate. Give Feedback
