The AOC 24G2SPU is a strong choice for casual and competitive gaming with its higher refresh rate and quick response time, enhancing smooth gameplay. However, the Dell S2721DS, with a larger screen and higher resolution, offers sharper images and more workspace for productivity and media consumption. Neither excel in HDR gaming or media. If gaming is a priority and you're on a budget, go for the AOC; for better image clarity in daily tasks and media, albeit at a slightly higher cost, choose the Dell. Give Feedback
