The ASUS ROG Strix G15 Advantage Edition offers strong performance for engineering and gaming due to its AMD Ryzen 9 processor and AMD RX 6800M GPU, along with a high refresh rate screen, making it well-suited for intensive tasks and gaming, but it's heavier and less portable. On the other hand, the Lenovo Legion Slim 5 is more affordable and lightweight, featuring a newer Nvidia RTX 4060 GPU for robust gaming and engineering capabilities, and it has slightly better battery life. It also has a higher screen aspect ratio which is better for productivity tasks. Consider the ASUS if performance for demanding tasks is your top priority and you don't mind the extra weight, or the Lenovo if you seek a balance of performance, portability, and value.

The ASUS ROG Strix G15 Advantage Edition has a better screen than the Lenovo Legion Slim 5 for general use, gaming and AI, and engineering and design.
For general use, the screen quality of both the ASUS and Lenovo is considered good due to their adequate resolution and brightness, providing clear and vivid display for everyday tasks like browsing and watching videos. In engineering and design, their screens are appreciated for covering a broad range of colors, ensuring accuracy in color-critical applications such as photo editing or CAD work. However, for gaming and 3D applications, their screens fall short because they have a lower refresh rate, which can limit the smoothness and responsiveness during fast-paced action and rendering.

How the ASUS ROG Strix G15 Advantage Edition and the Lenovo Legion Slim 5 compare to other laptops
"The Asus ROG Strix G15, as the first in a line of "AMD Advantage"-branded notebooks, is a statement that yes, you can get a premium AMD gaming notebook. Maybe you can't have it all, but you can get pretty close. The ROG Strix G15's combination of the AMD Ryzen 5900HX and Radeon RX 6800M, as well as other technologies that take advantage of them, make a potent, thin gaming machine. Powerful Dolby Atmos speakers and long battery life when you aren't gaming are nice bonuses."
"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."
