The ASUS ROG Strix G15 Advantage Edition leans more towards gaming and intensive tasks, with a stronger graphics setup but is heavier, which impacts portability. Conversely, the Lenovo Legion Slim 7 is lighter and has a brighter screen, which may be beneficial for day-to-day use and productivity tasks, with slightly lower performance in high-end gaming and intensive applications. The ASUS has better battery capacity, but both laptops have comparable battery life for typical usage. If gaming and performance for tasks like 3D rendering and engineering are the priority, the ASUS is a solid choice; for greater portability and everyday use with competent performance, consider the Lenovo.

How the ASUS ROG Strix G15 Advantage Edition and the Lenovo Legion Slim 7 15.6" 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 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
