Our Verdict

ASUS ROG Swift 360Hz PG259QN

Dell Alienware AW2523HF

The ASUS ROG Swift 360Hz PG259QN and the Dell Alienware AW2523HF are both 25-inch, 1080p gaming monitors with a 360Hz refresh rate. Because of their similar specs, they also have similar performance, but there are a few differences. The main difference is that the ASUS has native G-SYNC support while the Dell has native FreeSync support. It doesn't make much difference while gaming, except the native G-SYNC support on the ASUS monitor allows you to take full advantage of your NVIDIA graphics card. The Dell has better motion handling because there's a lot less overshoot, but the ASUS has a backlight strobing feature to further reduce persistence blur.
