If you prioritize portability and a touchscreen with a slightly lower price, the Dell Inspiron 14 7425 could suit your needs. However, if you're looking for better performance for gaming, 3D rendering, or machine learning and don't mind a slightly higher price and less portability, the Lenovo Legion Slim 7 15.6" would be a better choice with its higher-grade graphics and faster screen refresh rates. The Dell could be more convenient for general use and has good keyboard and build quality, while the Lenovo, with its superior color coverage and brightness, would better serve entertainment and professional creative work.

The Dell Inspiron 14 7425 offers a balance of resolution and brightness suitable for everyday tasks, but its color coverage may not be wide enough for precise engineering and design work, and its lower refresh rate can hinder the smooth visuals critical in gaming and 3D applications.

Jared Newman | December 2021
"Overall, this Dell Inspiron 14 2-in-1 offers a lot to like, especially at its oft-discounted price of $800. It’s a sturdy laptop with strong performance, a convertible touchscreen, loud speakers, and a convenient fingerprint reader. But the trade-offs you’ll make in pursuit of that lower price—most notably the dim display and stiff trackpad—might just keep you from outright loving it."

Benjamin Herzig | November 2022
"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."
