If you prioritize performance for tasks like 3D rendering, machine learning, or gaming, and don't mind a heavier laptop with a slightly shorter battery life, the Lenovo Legion Slim 5i with a powerful GPU and higher resolution display is a better fit. On the other hand, if you prefer a lighter, more portable option with a touchscreen for general use and better battery life, the Dell Inspiron 14 7425 is suitable, but it has less power for intensive tasks and a lower resolution screen. Both are similarly priced and offer good keyboards and build qualities, making them versatile for everyday tasks. Give Feedback

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."

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
