The ASUS ROG Strix G18 offers high performance, better suited for intensive gaming and engineering tasks with its advanced processor and higher-end graphics. However, it is less portable due to its larger size, heavier weight, and shorter battery life. In contrast, the Lenovo Legion Slim 7 is more affordable, lighter, and has a longer battery life which makes it convenient for on-the-go use and general activities. While capable for 3D tasks and engineering software, its performance is not as robust as the ASUS model. Consider the ASUS for demanding applications and the Lenovo if you prioritize portability and value. Give Feedback

The ASUS ROG Strix G18 is very good for general use, while the Lenovo Legion Slim 7 15.6" is good.
The ASUS ROG Strix G18, with its high-end CPU and GPU, large screen, and superior brightness, offers exceptional performance and screen quality for general use but is less portable and has lower battery life compared to the Lenovo Legion Slim 7 which, despite having a mid-range CPU and GPU, is more portable with better battery life, making it a balanced choice for general use tasks.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo Legion Slim 7 15.6" is good.
The ASUS ROG Strix G18 stands out for gaming and 3D applications thanks to its more powerful GPU, the Nvidia RTX 4070, and a higher screen refresh rate at 240Hz, offering smoother visuals in fast-paced games. In contrast, the Lenovo Legion Slim 7 15.6" has a more modest Nvidia RTX 3060 GPU and a 165Hz refresh rate, providing good gaming performance but at a potential visual and responsiveness compromise compared to the ASUS.

The ASUS ROG Strix G18 has a better screen than the Lenovo Legion Slim 7 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G18 offers a high-resolution display with a panel that delivers vibrant colors and excellent detail, making it ideal for tasks like photo editing or graphic design; however, its lower refresh rate may not be as suitable for the fast-paced visuals sought by gamers. The Lenovo Legion Slim 7 boasts similar screen characteristics good for detailed work and media consumption, but again, it doesn't prioritize the high refresh rates critical for smooth gaming and 3D rendering experiences. Both laptops may excel in offering crisp and accurate colors for professional applications, but they won't satisfy users looking for the fluid motion necessary for high-end gaming.

"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 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."
