If your focus is competitive gaming with the highest refresh rates and response times, the BenQ may be your preferred choice as it offers excellent gaming performance at a lower price. However, if you need a monitor that offers better overall image quality, color accuracy, and higher resolution for tasks such as media consumption or casual gaming, you might prefer the Asus despite its higher cost. Keep in mind that while the Asus also has a high refresh rate suitable for competitive gaming, it is pricier and may not be as cost-effective if gaming is your sole purpose. Give Feedback

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."

"It’s not for everyone in the same way that a top fuel dragster isn’t everyone’s perfect daily driver. The BenQ Zowie XL2566K succeeds in delivering the fastest, sharpest and smoothest display for pro FPS players and that’s all it wanted to do. Its other limitations and premium price tag mean it’s a bespoke tool for a niche market, rather than another general gaming monitor for those who like playing games."
