If you're a serious gamer looking for the ultimate experience with smooth motion and great contrast, particularly in dark scenes, and don't mind spending more, then the AOC AG456UCZD with its larger screen and OLED panel is a strong choice. However, if high-resolution content and sharp text are more important for productivity and you're looking for a balance between gaming, media consumption, and work, the Sony M9 would be a better fit at a lower price point. The AOC may not perform as well for tasks that require color accuracy, like photo editing, where the Sony M9 shines, despite its lower gaming performance. Give Feedback
