The ASUS ROG Strix G15 is a bit less expensive, with solid performance for general use and gaming. However, it's heavier and has shorter battery life compared to the Lenovo Legion Slim 7 16", which is a newer model with a more powerful graphics card, making it better for 3D work, machine learning, and intensive engineering tasks. The Lenovo also has a higher resolution screen with better color accuracy, and it is thinner and lighter, improving portability. If budget and gaming are your primary concerns, the ASUS could be suitable, but for high-end tasks and better portability, the Lenovo is the superior option. Give Feedback

The Lenovo Legion Slim 7 16" is very good for gaming and AI, while the ASUS ROG Strix G15 is good.
The Lenovo Legion Slim 7 16" outperforms the ASUS ROG Strix G15 in gaming and 3D due to a superior GPU and a higher screen refresh rate, which are very important for these tasks, while also featuring a solid CPU and higher-quality screen which contribute to overall performance and visual experience. Despite the importance of the CPU and screen quality, the Legion's advantages in the GPU and refresh rate hold more weight for gaming and 3D applications, setting it apart from the ASUS ROG Strix G15.

The Lenovo Legion Slim 7 has a better screen than the ASUS ROG Strix G15 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS ROG Strix G15's strength lies in its sufficient resolution and brightness, making it suitable for general tasks and detailed work in engineering and design due to accurate color representation. The Lenovo Legion Slim 7's screen offers even higher resolution and brightness, complemented by wide color gamuts, ensuring vivid and precise colors critical for professional design work. However, both laptops fall short for gaming and 3D applications because their screens have lower refresh rates, which can limit the smoothness and responsiveness necessary for high-speed visuals in such scenarios.

"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
"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."
