The Dell Inspiron 16 5635 is often significantly less expensive and offers a higher resolution display with a larger screen size, which is great for productivity and multimedia use. It also has a larger battery capacity, providing longer unplanned usage, but it is equipped with integrated graphics which are fine for everyday tasks but not ideal for gaming or intensive 3D tasks. On the other hand, the Lenovo Legion Slim 7 has a more powerful main processor and dedicated Nvidia graphics, making it better suited for gaming, 3D rendering, and machine learning tasks. Its smaller screen and lower resolution might be less suited for detailed engineering work, but its higher refresh rate will benefit fast-paced gaming. The tradeoff here is between better gaming and intensive task performance in the Lenovo at a higher price versus the Dell's affordability and higher resolution, larger screen for general productivity.

Although they have very similar scores, PerfectRec considers Dell Inspiron 16 5635 to be very good for general use, while the Lenovo Legion Slim 7 15.6" is good.
The Dell Inspiron 16 5635 is deemed very good for general use partly due to its high-resolution display, providing clear and sharp images, and considerable storage for documents and media, but it has a moderate battery life which may require more frequent charging.

UltrabookReview
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."

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."
