The ASUS ROG Strix G18 offers high performance for intensive tasks like 3D rendering, machine learning, and engineering, also proving excellent for gaming due to its robust GPU and CPU. It is, however, more expensive and heavy which may affect portability. The Lenovo ThinkBook 13s, while more affordable and lightweight, making it highly portable and suitable for general use, is not tailored towards heavy tasks or gaming as it has less storage and a less powerful integrated GPU. Both devices offer high-resolution displays but the ASUS has a larger screen and higher refresh rate, tailored more towards gamers and professionals needing a bigger workspace. Give Feedback

The ASUS ROG Strix G18 is very good for general use, while the Lenovo ThinkBook 13s is good.
The ASUS ROG Strix G18 stands out for general use with its higher-end CPU and dedicated graphics unit, leading to smoother multitasking and better handling of graphically intense tasks, though it is less portable and has a shorter battery life compared to the Lenovo ThinkBook 13s, which offers a good balance of performance for general tasks, superior portability, and longer battery life, but with integrated graphics that are less suited for demanding applications. Both laptops have comparable RAM and high-quality screens, but tradeoffs in portability and performance differentiate them for general use.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo ThinkBook 13s is only fair.
The ASUS ROG Strix G18 is superior for gaming and 3D applications primarily because it features a powerful Nvidia RTX 4070 graphics card and a high screen refresh rate of 240Hz, enhancing visual fluidity and detail during fast-paced action. The Lenovo ThinkBook 13s, while still capable, offers a more modest Intel Iris Xe graphics solution and a standard refresh rate of 60Hz, adequate for general use but not optimized for the high-performance demands of intense gaming and 3D work.

The ASUS ROG Strix G18 has a better screen than the Lenovo ThinkBook 13s for general use, gaming and AI, engineering and design, software development, and content creation.
Both the ASUS ROG Strix G18 and the Lenovo ThinkBook 13s offer high-resolution displays with strong brightness and suitable panel types for clear and vivid images, making them excellent for general use and engineering tasks that benefit from accurate color representation. The ASUS stands out for engineering and design due to its wider color gamut coverage, essential for precise color work. However, for gaming and 3D applications, the lower refresh rate on both laptops can lead to less fluid motion and diminished responsiveness, which is less ideal for fast-paced visuals that rely on quick screen updates.

How the ASUS ROG Strix G18 and the Lenovo ThinkBook 13s compare to other laptops
"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 best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
