Our Verdict

Dell Alienware AW2521HF

ASUS ROG Swift 360Hz PG259QN

The ASUS ROG Swift 360Hz PG259QN is a bit better than the Dell Alienware AW2521HF. The ASUS has a higher refresh rate, better color accuracy out of the box, and better gradient handling. The Dell Alienware has wider viewing angles, and although its response time is slightly slower, there's significantly less overshoot.
