If you prioritize gaming or demanding tasks such as video editing or 3D modeling, the ASUS ROG Strix, known for high-end performance and advanced graphics, would be a strong choice, albeit at a higher cost and with likely less battery life and portability. Conversely, the Lenovo IdeaPad Slim 7i, while more affordable and lightweight for easy travel, is better suited for everyday tasks and lighter workloads. Consider the Lenovo if you prefer a slimmer design and longer battery for general use, but choose ASUS if performance for more resource-intensive applications is essential, despite the added weight and investment.

The ASUS ROG Strix G18 (2024) is very good for general use, while the Lenovo IdeaPad Slim 7i is good.
The ASUS ROG Strix G18, with its high-end CPU and ample RAM, excels in intensive tasks and delivers excellent screen quality, but its size and shorter battery life make it less portable.

The ASUS ROG Strix G18 (2024) is very good for gaming and AI, while the Lenovo IdeaPad Slim 7i is only fair.
The ASUS ROG Strix G18 comes equipped with a high-end GPU and a faster screen refresh rate, making it well-suited for demanding gaming and 3D tasks, where graphics and smooth motion are key. On the other hand, the Lenovo IdeaPad Slim 7i, while having a decent CPU and screen quality, does not match the ASUS in terms of graphical power and refresh rate, which makes it less ideal for high-performance gaming and 3D applications.

The ASUS ROG Strix G18 has a better screen than the Lenovo IdeaPad Slim 7i for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Strix G18 likely has a high-resolution display with excellent color reproduction and brightness, making it well-suited for general tasks and engineering design work where visual precision is key. However, its low refresh rate is a disadvantage for gaming and 3D applications where smooth motion is crucial. Conversely, the Lenovo IdeaPad Slim 7i, while still providing adequate resolution and color for general use and professional design, falls short for gaming and 3D work due to similar limitations in refresh rate.

"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."
"Among Lenovo's multiple laptop brands, the IdeaPad family is decidedly the one designed for consumers: people who want decent performance at a reasonable price. Consider, then, this laptop a paragon for the pickier members of that crowd. With a 14-inch touch-enabled display, a comfortable keyboard, an Evo-certified Intel Core i7 11th Generation CPU, and the latest Windows 11 operating system, the IdeaPad Slim 7i Pro ultraportable ($1,199 as tested) is a slick mainstream machine at a bit of a premium price, and quite capable for everyday tasks."
