Our Verdict
AOC 24G2
Dell S2421H
The AOC 24G2 is much better than the Dell S2421H. The AOC is much better for every use, but it's especially better for gaming. The AOC has a faster refresh rate, and a significantly faster response time, resulting in clearer motion with less blur behind fast-moving objects. The AOC also has much better ergonomics, so it's easier to place it in an ideal viewing position.
