If you're on a budget and need a laptop for everyday tasks like web browsing, word processing, and light productivity work, the Dell Latitude 14 7490 could be a suitable option due to its typically lower price. But, if you require a machine for more demanding tasks such as gaming, 3D modeling, machine learning, or engineering software, the Lenovo Legion Slim 7 16" would be more appropriate despite the higher cost, as it likely offers better performance and graphics capabilities. However, keep in mind that the Lenovo may also be heavier and have a shorter battery life than the Dell, which could affect portability and convenience for on-the-go use. Give Feedback

The Lenovo Legion Slim 7 has a better screen than the Dell Latitude 14 7490 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, a laptop like the Dell Latitude 14 7490 with a fair screen quality will have acceptable resolution and brightness, making it suitable for everyday tasks like browsing and office work; however, the Lenovo Legion Slim 7's very good screen excels in these areas, providing sharper images and better visibility in various lighting conditions. When considering engineering and design work where color accuracy is pivotal, the Dell has good screen quality due to reasonable coverage of professional color gamuts, but the Lenovo stands out with very good color reproduction, making it more suitable for tasks that require precise color matching. For gaming and 3D work, despite their high resolutions and panel types, both the Dell and Lenovo offer poor experiences because they lack high refresh rates, which are crucial for smooth motion and gameplay.

"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 Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
