If you favor performance for tasks like 3D rendering, machine learning, and engineering, the Lenovo Legion Slim 5i with its powerful graphics chip could be a better choice. On the other hand, the ASUS Zenbook Pro 17 offers solid general use performance with ample RAM for multitasking. The Zenbook also boasts a larger screen but with a lower resolution and refresh rate compared to the Legion, which could be important if you prioritize visual work or gaming. The Lenovo is likely more suited to gaming thanks to its higher-end GPU and superior screen specs. The ASUS, being slightly lighter and thinner, may offer better portability, although both laptops provide sufficient battery life for typical use. Your decision should hinge on whether you need higher graphical performance or prefer a larger display and potentially better multitasking with the additional RAM. Give Feedback

The ASUS Zenbook Pro 17 has a better screen than the Lenovo Legion Slim 5i for content creation, while the Lenovo Legion Slim 5i has a better screen for general use, gaming and AI, and engineering and design.
The ASUS Zenbook Pro 17 offers a display with high resolution and brightness, making it pleasant for general tasks like web browsing and document editing, but its modest refresh rate impacts the smoothness required in fast-paced gaming scenarios. The Lenovo Legion Slim 5i, while boasting superior screen quality for everyday activities through a combination of resolution and visibility in different lighting conditions, falls behind for gaming as the refresh rate does not cater to the high frame rates gamers seek. For engineering and design, both displays provide wide color coverage essential for precision work, though neither hits the top mark required by the most color-critical tasks like professional video editing or 3D rendering.

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."
