If you prioritize competitive gaming and want to save money, the Asus PG279QM offers a higher refresh rate that is beneficial for fast-paced games. However, for a premium, the Dell Alienware AW3423DW provides an exceptional contrast with its OLED panel which enhances HDR gaming and media viewing with deeper blacks and vibrant colors. The Alienware's ultra-wide screen also offers a more immersive experience but might not suit all desks or workflows. Remember, the Asus has better text clarity for productivity, while the Dell excels in color performance for media. Choose based on whether competitive gaming, immersive media experiences, or budget is your priority. Give Feedback
