If you prioritize high-end gaming or demanding tasks and don't mind spending more, the ASUS ROG Strix could be a better choice; however, if you prefer something lighter and more mobile with a generally lower cost, the Lenovo Legion Slim 5 offers a good balance between performance and portability for everyday use and less intense workloads. Keep in mind, the ASUS may have shorter battery life due to its more powerful components, while the Lenovo could last longer on a single charge, making it more suitable for on-the-go use.

The ASUS ROG Strix G16 has a better screen than the Lenovo Legion Slim 5 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G16 boasts a higher resolution and superior brightness, making its screen vibrant and sharp for general tasks and detailed work in engineering and design, but its lower refresh rate limits its appeal for gaming and 3D applications where smoother motion is crucial.

Marc Herter | March 2023
"With the mobile Nvidia GeForce RTX 4080, the Asus ROG Stix G16 hits the sweet spot between performance and cooling. The G16 also does not have to shy away from direct comparison with its supposedly stronger family member, the ROG Strix Scar 18 with its RTX 4090, as most benchmarks of the two laptops are very close to each other. Moreover, the G16 should be significantly cheaper. Depending on the supplier, the price difference here could be almost US$ 2,000. In the 2023 model series, Asus has significantly leveled out the differences between the two high-end lines."

"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."
