If the main concern is budget and general use, the Dell Latitude is a more economical option and provides solid performance for everyday tasks like web browsing, office applications, and video streaming. However, if you require high performance for gaming, 3D rendering, or intensive engineering tasks, the Lenovo Legion has more powerful hardware but comes at a higher price and may be heavier, impacting portability. The Dell would typically offer longer battery life, appealing for users who need to work on the go, while the Lenovo's battery life might be shorter due to its high-performance components.

"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."

"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
