Our Verdict
Dell Alienware AW2521H
MSI Oculux NXG253R
The Dell Alienware AW2521H and the MSI Oculux NXG253R are extremely similar overall, but the Dell is slightly better overall. The Dell has a slightly faster response time, it's brighter, and the unit we bought has better accuracy out of the box, but this can vary between units. On the other hand, the MSI has a wider swivel range.
