The Lenovo Legion Slim 5i is very good for engineering and design, while the Dell Latitude 5431 is only fair.
The Lenovo Legion Slim 5i stands out for engineering and design use due to its higher-tier Intel i7 processor, significantly more powerful Nvidia RTX 4060 GPU, and a higher resolution display which is crucial for these tasks. In contrast, the Dell Latitude 5431, while suitable for business applications, has a lower-end Intel i5 processor and integrated graphics, making it less ideal for engineering and design tasks that often require more processing power and advanced graphical capabilities.

The Lenovo Legion Slim 5i has a better screen than the Dell Latitude 5431 for general use, gaming and AI, engineering and design, content creation, and software development.
The Dell Latitude 5431's screen, with modest brightness and standard resolution, suffices for everyday tasks but may lack the vibrancy and clarity needed for precise engineering work or the immersive experience desired in gaming due to mediocre color accuracy and absence of high refresh rates. In contrast, the Lenovo Legion Slim 5i offers a very good display for daily activities with its higher resolution and brightness, and while it provides richer colors that benefit engineering and design applications, its lower refresh rate still falls short for the demanding, fluid visuals crucial in gaming and 3D environments. Therefore, the Dell is a budget-friendly choice for basic use, whereas the Lenovo is a more versatile, yet still not gaming-optimized, option for those requiring better color reproduction and crisper details.

PCMag
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."
