If competitive gaming is a priority and you're looking to save money, the Asus PG27AQN with its high refresh rate and low response time would be a strong choice. However, if you value stunning visuals for HDR gaming and media, and are willing to invest more, the MSI MAG 321UPX with its superior contrast, color range, and higher resolution will offer a more immersive experience. The MSI's larger screen and higher resolution make it better for productivity and content creation, especially in digital photo and HDR video editing, given its wide color gamut coverage.

IGN
Matthew Smith | March 2023
"The Asus ROG Swift PG27AQN is a motion clarity marvel. It’s the first 27-inch 1440p 360Hz monitor on the market, and also the first to use an Ultrafast IPS display. These advancements provide outstanding motion clarity across a broad range of refresh rates. Unfortunately, the monitor’s motion clarity does nothing for its image quality, which is just ok. To be clear, it’s a very nice looking monitor in many situations. However, the monitor’s contrast ratio is rather low. And while it can reach high levels of brightness in HDR, it lacks the nuance and contrast required to look great in HDR games."
