The Dell Inspiron 16 5635 may save you money and offers a fanless operation which means it runs silently, but it has a lower performing graphics unit compared to the Lenovo Legion Slim 5. If you require higher graphics performance, as for gaming or graphic design, the Lenovo, with its dedicated Nvidia RTX graphics card, will serve you much better despite being slightly more expensive. However, the Dell has a higher resolution screen, which may be preferable for tasks like video editing or if you prefer crisp visuals. Keep in mind that the Lenovo may offer better overall performance due to its dedicated graphics card. If battery life and portability are important to you, consider that the Lenovo has a larger battery but also is heavier, which may affect how easy it is to carry around. Additionally, the Dell's silent, fanless operation could be an advantage if you need to work in quiet environments. Give Feedback

The Lenovo Legion Slim 5 is very good for engineering and design, while the Dell Inspiron 16 5635 is good.
The Lenovo Legion Slim 5 stands out for engineering and design use due to its more powerful Nvidia RTX graphics card which is better for demanding tasks compared to the integrated Vega 8 GPU in the Dell Inspiron 16 5635. While the Dell Inspiron has a high-quality display and is lighter for portability, the Lenovo's superior display brightness, higher color coverage which indicates better screen quality, and a stronger contrast ratio make it more suitable for detailed visual work.

Although they have very similar scores, PerfectRec considers Dell Inspiron 16 5635 to be very good for general use, while the Lenovo Legion Slim 5 is good.
The Dell Inspiron 16 5635 is very good for general use due to its ample high-speed CPU and RAM, superior screen quality with higher resolution and color coverage, and lighter weight enhancing its portability, despite having a shorter battery life than the Lenovo. While the Lenovo Legion Slim 5 is also good for general use, with a powerful CPU and ample RAM, its gaming-focused hardware, heavier build, and louder operating noise may not appeal to those seeking a quieter and more transportable daily work laptop.

Derek Sullivan | January 2023
"Compared to the previous year’s Inspiron, Dell upgraded the screen aspect ratio on this generation, but also transitioned to a more minimalistic centered keyboard flanked by up-firing speakers. The 16-inch screen is huge plus and I really appreciate the extra real estate without sacrificing the footprint much. This year’s model is a little larger than last, though, as the former model was already very small for a 15 incher."

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."
