The ASUS ROG Strix G18 (2024) is very good for general use, while the Lenovo IdeaPad Slim 3 is good.
The ASUS ROG Strix G18, with its superior CPU and RAM, excels at demanding tasks and provides a vibrant screen for an engaging user experience, but it trades off portability and battery life due to its gaming-oriented design. The Lenovo IdeaPad Slim 3, while more portable and with longer battery life, offers modest performance that's adequate for everyday activities, yet it falls short for more intensive applications and doesn't match the screen quality of the ASUS.

The ASUS ROG Strix G18 (2024) is very good for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The ASUS ROG Strix G18, with its advanced GPU and high screen refresh rate, outshines the Lenovo IdeaPad Slim 3 in gaming and 3D tasks, leading to smoother visuals and better overall performance. While the IdeaPad Slim 3 may suffice for casual use due to its adequate CPU and screen quality, it can't compete with the ASUS's superior specs tailored for intense graphic demands.

The ASUS ROG Strix G18 (2024) is excellent for engineering and design, while the Lenovo IdeaPad Slim 3 is only fair.
The Asus ROG Strix G18 boasts a high-end CPU, substantial RAM, and a powerful GPU, all of which are crucial for smooth engineering and design tasks, along with a high-quality screen for clear visuals, whereas the Lenovo IdeaPad Slim 3 has modest specs in comparison, making it less suitable for demanding tasks. Despite its superior performance, the Asus is less portable due to its size and weight, and both laptops offer different keyboard and speaker qualities, with the Asus possibly having a louder operating noise due to its advanced cooling requirements for heavier workloads.

The ASUS ROG Strix G18 has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS offers a high-resolution display with excellent brightness and color, making text and images crisp and vivid, while the Lenovo provides decent clarity and is suitable for everyday tasks but may lack sharpness and vibrancy. When it comes to engineering and design, the ASUS stands out with a wide color gamut that accurately reproduces colors necessary for professional work, while the Lenovo has an adequate range but may not meet the precision required by professionals. However, in Gaming and 3D scenarios, the high refresh rate is critical, and this is where the ASUS falls short, leading to less fluid motion, whereas the Lenovo also fails to provide the fast refresh needed for a smooth gaming experience.

"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."
Olivier Martin, Ryan Lim, and John Peroramas | May 2023
"The Lenovo IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
