If competitive gaming and fast response times are top priorities, and you're looking to save a bit of money, the Asus PG279QM with its high refresh rate could be a good fit. However, for a premium, the Dell Alienware AW3423DWF offers deeper blacks and vibrant colors with its QD-OLED panel, enhancing HDR gaming and media consumption. Its wider screen and aspect ratio also make it more suited for immersive experiences and multitasking, but it might not be as suitable for tasks like digital photo editing because of its glossier screen and slight tradeoff in text clarity compared to the Asus.

"It may seem like a minor tweak, but the addition of a glossy anti-glare coating makes all the difference. It really lets the OLED panel rip. That this revised "F" model is also cheaper than the OG Alienware OLED and the similarly glossy Philips competition seals the deal. This is our new favourite among the OLED monitor massive."
