The ASUS ROG Strix G18 has a better screen than the Lenovo Legion Slim 7 for software development, and content creation.
The ASUS ROG Strix G18 and Lenovo Legion Slim 7 both offer high-resolution, bright displays with panel types suited for vivid colors and sharp details, making them excellent for general use and satisfying the needs of professionals in engineering and design who rely on accurate color reproduction. Despite their strengths, they are less ideal for Gaming and 3D because they lack the high refresh rates necessary for smooth motion and fast-paced visuals typical in these applications. Screen quality for Gaming and 3D is not solely about clarity and color fidelity, but also how quickly the screen can update, which is crucial for an immersive and responsive experience.

How the ASUS ROG Strix G18 (2024) and the Lenovo Legion Slim 7 16" 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 Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
