The Dell S2721DS is budget-friendly and suitable if you mainly do everyday tasks, non-competitive gaming, or standard office work on your monitor. However, for a better experience with HDR gaming, media consumption, productivity with high-quality visuals, and a sharper image due to a higher resolution, the Sony M9 would be the superior choice. Keep in mind that while the Sony provides more advanced features and significantly better performance in various areas, this comes at a higher cost. If those enhanced capabilities align with your needs and you're willing to invest more, the Sony M9 would be the better option. Give Feedback
