Choosing between the ASUS ROG Strix G18 and the Lenovo Legion 7i Pro involves several considerations. The ASUS model offers RGB keyboard lighting, a higher contrast ratio, and slightly superior brightness, which can make the screen more vivid for gaming and entertainment. In contrast, the Lenovo boasts more RAM for better multitasking and a slightly higher battery capacity for prolonged use, as well as a smaller power brick making it a tad more travel-friendly. Both laptops are similarly priced and have robust processing power suitable for engineering, gaming, and intensive 3D and machine learning tasks. If weight is a concern, the Lenovo is lighter, and it also has a higher portability score, making it a better option if you move around often. However, the ASUS has a slightly longer battery life and a higher general use performance, which could be advantageous for extended work sessions without a power source. Give Feedback

The Lenovo Legion Pro 7i and ASUS ROG Strix G18 are both very good for general use.
The ASUS ROG Strix G18 offers a large, high-quality screen, a potent CPU and significant RAM, lending to its impressive general-use capabilities, though its size and weight reduce its portability and its battery life is limited compared to some peers. The Lenovo Legion 7i Pro, while slightly more portable and with longer battery life, boasts an equally strong CPU, more RAM for multitasking, and a similar quality screen, but like the ASUS, the increased performance and screen quality can result in a tradeoff with portability.

"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."

"Passionate gamers who want to play demanding modern titles with maximum details and don't mind spending the moolah will find the Lenovo Legion 7 Pro to be the right choice. The bright, sharp, and color-accurate 16:10 QHD 240 Hz display makes for an immersive viewing experience. The hardware is housed in a stylish chassis that feels premium and scores well in terms of workmanship and stability. Other aspects such as sound quality, input devices, and connectivity also seem to be near-perfect."
