The ASUS ROG Strix G18 is very good for general use, while the Lenovo IdeaPad Slim 3 is good.
The ASUS ROG Strix G18 outperforms the Lenovo IdeaPad Slim 3 for general use due to its powerful Intel i9 processor, ample RAM, superior screen resolution and quality, but it falls short in portability and has a lower battery life, which may be a concern for those who frequently move around.

The ASUS ROG Strix G18 is very good for gaming and AI, while the Lenovo IdeaPad Slim 3 is poor.
The ASUS ROG Strix G18 provides a superior gaming and 3D experience mainly because it has a high-end Nvidia RTX 4070 GPU and a very high screen refresh rate of 240Hz, delivering smoother visuals and better performance in graphics-intensive tasks. In contrast, the Lenovo IdeaPad Slim 3 is equipped with an integrated AMD Vega 6 GPU and a standard refresh rate of 60Hz, which is adequate for less demanding games and tasks but can't match the ASUS's performance for more intensive applications.

The ASUS ROG Strix G18 is very good for engineering and design, while the Lenovo IdeaPad Slim 3 is only fair.
The ASUS ROG Strix G18, with its high-end Intel processor, ample RAM, and powerful Nvidia GPU, delivers the robust performance and superior screen quality needed for complex engineering and design tasks. In contrast, the Lenovo IdeaPad Slim 3 features a mid-range AMD processor and integrated graphics, which along with lower RAM, makes it less suitable for demanding engineering applications, despite its better portability and quieter operation.

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.
The ASUS ROG Strix G18 likely offers a high-resolution display with vibrant colors and ample brightness suitable for everyday tasks and detailed engineering work, but its refresh rate, which is crucial for smooth gaming and 3D rendering, may be lacking. On the other hand, the Lenovo IdeaPad Slim 3 probably has a decent display for everyday use and design tasks, with acceptable color accuracy and brightness, but falls short for gaming or 3D use due to a lower refresh rate and potentially less striking color range. Both laptops sacrifice gaming and 3D performance in terms of screen refresh rates, but make up for this in general use and engineering with good color reproduction and resolution.

"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."
