The ASUS ROG Strix G18 offers top-tier performance with its advanced processor and graphics card, which are well-suited for intensive tasks like 3D rendering, machine learning, and high-end gaming. However, it comes with a premium price, is larger at 18 inches, and is heavier, which impacts portability. On the other hand, the Lenovo Legion 5 15" is more budget-friendly and offers good performance for general use and moderate gaming. It is also more portable due to its smaller size and lighter weight. Ultimately, if budget is a concern and portability is important, the Lenovo is a strong choice, whereas if performance is a priority and cost less of an issue, the ASUS is the better option.

The ASUS ROG Strix G18 is very good for general use, while the Lenovo Legion 5 15" is good.
The ASUS ROG Strix G18 excels in general use with a more powerful CPU, larger high-resolution screen, and higher RAM capacity, which greatly benefit multitasking and media consumption; however, it has less portability and shorter battery life compared to the Lenovo Legion 5 15", which offers a balance of performance for general use with a capable CPU and enough RAM, in a more compact form with longer unplugged usage. The Lenovo Legion also has a good quality screen, but the ASUS edges out with superior color coverage and brightness, making it better for visually intensive tasks.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo Legion 5 15" is good.
The ASUS ROG Strix G18 is very good for gaming and 3D due to its superior Nvidia RTX 4070 GPU and a higher screen refresh rate of 240Hz, providing smoother visuals and better gaming performance. On the other hand, the Lenovo Legion 5 15" has a slightly less powerful Nvidia RTX 4060 GPU and a lower refresh rate of 165Hz, which still offers good gaming and 3D capabilities but might not be as visually fluid or perform as well in the most demanding scenarios.

The ASUS ROG Strix G18 has a better screen than the Lenovo Legion 5 15" for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, both the ASUS ROG Strix G18 and Lenovo Legion 5 provide clear, bright displays with high resolution, ensuring sharp and vibrant images for everyday tasks. Engineers and designers would prefer the ASUS with its superior color accuracy and wider color gamut, presenting more precise colors for professional work. However, gamers may find both lacking due to their lower refresh rates, which could result in less fluid motion during fast-paced gaming or 3D modeling scenarios.

"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 5 15 is an affordable gaming laptop with a lot of power. The new AMD processor Ryzen 7 5800H offers plenty of performance and it is also very efficient. The combination with the fast 130W version of the GeForce RTX 3060 ensures high gaming performance. We also like the fast 165 Hz display with the 1080p resolution. The automatic graphics switching causes some problems with stutters, which are very annoying. If you do not need long battery runtimes, you should definitely deactivate the hybrid graphics mode in Lenovo's Vantage app. The Legion 5 15 is never silent."
