The Lenovo Legion Slim 7 16" is very good for engineering and design, while the Dell Inspiron 16 5635 is good.
The Lenovo Legion Slim 7 16" is very good for engineering and design due to its powerful AMD Ryzen CPU, superior Nvidia RTX GPU, and higher screen brightness, which enhance performance and visual clarity for complex tasks. In comparison, the Dell Inspiron 16 5635 is considered good for these uses, as it offers a decent Ryzen CPU with integrated graphics and a good-quality screen but falls short in GPU performance and screen brightness, which are critical for demanding engineering and design applications.

The Lenovo Legion Slim 7 has a better screen than the Dell Inspiron 16 5635 for general use, gaming and AI, engineering and design, content creation, and software development.
If you prioritize a crisp and vivid display for everyday tasks like browsing or watching videos, the Lenovo Legion Slim 7's high resolution and brightness will enhance your experience more than the Dell Inspiron. For professionals in engineering or design work, the Lenovo's wider color range will ensure more accurate color representation, which is crucial for precise visual work.

How the Dell Inspiron 16 5635 and the Lenovo Legion Slim 7 16" compare to other laptops
"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."
"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."
