Our Verdict
ASUS TUF Gaming VG259QM
Dell Alienware AW2521H
The ASUS TUF Gaming VG259QM is slightly better for gaming than the Dell Alienware AW2521H. The ASUS has significantly better ergonomics, a bit better reflection handling, a wider BFI flicker range, and it has built-in speakers. However, the Dell has a higher 360Hz refresh rate, better response time, and slightly lower input lag.
