The ASUS ROG Strix G18 is a great choice if you prioritize a high-performing machine for gaming or intensive tasks like 3D rendering or engineering software, and if you prefer a larger, high-refresh rate display. However, it is heavier, less portable, and also more expensive. On the other hand, the Lenovo IdeaPad 5 15" is more budget-friendly and offers good battery life, making it suitable for general use and portability, but it has a lower performance capability compared to the ASUS, which may not be as suitable for high-end gaming or resource-intensive applications. The Lenovo also features a touchscreen, which the ASUS lacks. Give Feedback

The ASUS ROG Strix G18 has a better screen than the Lenovo IdeaPad 5 15" for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G18, with a display that excels in brightness and resolution, provides clear and vivid visuals that are important for general use and detailed work in engineering and design. However, its lower refresh rate makes fast-moving images in gaming and 3D applications less smooth, which can be a drawback for those specific activities. In contrast, the Lenovo IdeaPad 5 15" offers adequate screen quality with modest brightness and resolution suitable for everyday tasks and some technical work, but its limited color range and refresh rate may not satisfy professionals in design fields or gamers seeking immersive experiences.

"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 IdeaPad 5 is convincing due to its long battery life. The device scores points especially with its large battery and long battery runtimes combined with its low consumption. The CPU and GPU perform in the test as one would expect, and in line with what was familiar from the somewhat smaller 14-inch sister model, the Lenovo IdeaPad 5 14."
