If performance in gaming or resource-heavy tasks is a priority and budget is less of a concern, the ASUS ROG Strix G18 is a solid choice; however, its size and weight reduce its portability. On the other hand, if you're looking for something easier to carry around and less expensive, the Lenovo Legion Slim 5i is a good option, but be aware it may not handle intensive tasks as smoothly as the ASUS. The ASUS may also have a more robust cooling system, which could be a deciding factor for long gaming sessions or heavy software use. Give Feedback

The ASUS ROG Strix G18 has a better screen than the Lenovo Legion Slim 5i for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS and Lenovo both offer clear, crisp displays with high resolution and vibrant colors, making activities like browsing the web or watching videos pleasurable. When it comes to engineering and design, both laptops have panels that cover a wide color spectrum, ensuring accurate color reproduction, which is critical for tasks such as photo editing or CAD work. However, for gaming and 3D applications, their screens fall short due to lower refresh rates, which can cause motion blur and hinder the smoothness of fast-paced action.

"With the ROG Strix G18, Asus has made an almost consistently good debut in the still quite new 18-inch laptop segment. The base unit case shows a few signs of weakness in the area of stability and is something which has an effect on the perceived quality of the input devices (the chassis tends to rattle a bit). Nevertheless, thanks to generous port features (incl. Thunderbolt 4), a striking design, and extensive lighting (keyboard, LED strip on the front), gamers get a fitting gaming platform."
"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."
