The Dell Latitude 5431 offers a newer processor and a support for a modern operating system which may result in better performance for demanding tasks, but it is more expensive. The Dell Latitude 14 7490 includes a larger storage capacity and comes with a slightly older, but still capable processor, and it might offer better value for general use, especially if budget is a consideration. The 14 7490 is also marginally lighter, which might be preferable for portability, while the 5431 likely has some additional features aligned with its higher price. Ultimately, if newer technology and potentially better performance are priorities and you're willing to invest more, go with the Latitude 5431; if you're looking for a cost-effective option that still meets general use requirements, the Latitude 14 7490 may suffice.

Henry T. Casey | April 2018
"The Dell Latitude 7490's got the speed you need (and then some), a keyboard that's comfortable enough for writing all day long and a battery that supports a full 8-hour workday. If only the display were brighter and it managed heat better. If you need every minute of battery life you can get, the extended-battery version of the Lenovo ThinkPad T480 lasts 8 hours longer than the Latitude 7490, but its display is much less colorful."
