The ASUS ROG Strix G15 Advantage Edition is better suited for gaming and intensive tasks due to its powerful processor and graphics card, but the tradeoff is it's heavier and has a lower screen resolution compared to the Lenovo Legion Slim 5i. On the other hand, the Legion Slim 5i offers a higher screen resolution and is lighter, making it more portable, with the tradeoff being a less powerful GPU and CPU compared to the ASUS. The ASUS is often more expensive, but it has a longer battery life for extended use without charging. If portability and screen quality are important for general use and professional tasks, the Lenovo might be the better choice, but if gaming and performance take priority and you don't mind the extra weight and cost, the ASUS could serve you better.

The ASUS ROG Strix G15 Advantage Edition has a better screen than the Lenovo Legion Slim 5i for gaming and AI, while the Lenovo Legion Slim 5i has a better screen for general use, engineering and design, content creation, and software development.
The ASUS ROG Strix G15 Advantage Edition offers a balance between resolution and panel type suited for general use, though it may not stand out for gaming due to its lower refresh rate. The Lenovo Legion Slim 5i's very good screen quality in general use is due to its combination of high resolution, brightness, and quality panel type. However, both laptops lack the higher refresh rates preferred for 3D applications, which may disappoint gamers, and while suitable for engineering with good color accuracy, they can't match the top-tier screens designed explicitly for professional design work.

The Lenovo Legion Slim 5i and ASUS ROG Strix G15 Advantage Edition are both good for general use.
The ASUS ROG Strix G15 Advantage Edition offers solid performance due to its high-end CPU and ample RAM, which are key for multitasking and demanding tasks, while the quality IPS screen supports good color coverage and high refresh rates, enhancing visual experience; however, it trades off some portability with a heavier weight and larger size. On the other hand, the Lenovo Legion Slim 5i combines a strong CPU and plenty of RAM for smooth general use, and its superior screen resolution and aspect ratio provide enhanced clarity and workspace, further complemented by better portability owing to its lesser weight and comparable thickness, though at the expense of slightly shorter battery life.

Although they have very similar scores, PerfectRec considers Lenovo Legion Slim 5i to be very good for gaming and AI, while the ASUS ROG Strix G15 Advantage Edition is good.
The ASUS ROG Strix G15, with its AMD Ryzen CPU and RX 6800M GPU, delivers robust gaming performance with a high screen refresh rate, yet the Lenovo Legion Slim 5i's newer Intel CPU and Nvidia RTX 4060 GPU may provide an edge in both gaming performance and screen quality owing to its higher resolution and color accuracy. While the ROG Strix G15's higher refresh rate benefits fast-paced games, the Legion Slim 5i combines gaming prowess with a superior screen, making it very good for both gaming and 3D tasks.

How the ASUS ROG Strix G15 Advantage Edition and the Lenovo Legion Slim 5i 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."
