If you're looking for immersive media consumption and HDR gaming, the MSI MAG 271QPX offers superior contrast and color performance along with a very fast refresh rate that's excellent for competitive gaming. The Dell Alienware AW3821DW, despite its higher price, provides a larger, ultrawide screen which could be better for multitasking and productivity, but its overall picture quality and responsiveness might not be as impressive as the MSI's. Depending on whether your focus is on gaming and media or productivity and workspace, the MSI could be better for the former, while the Dell might suit the latter despite the cost difference.
