If you are looking for a laptop that excels in general use with an excellent display, the ASUS Vivobook S 15 OLED with its OLED screen, high brightness, and high contrast ratio is a good choice and generally costs less. However, the Lenovo Slim Pro 9i, while usually more expensive, brings more power for 3D rendering, machine learning, and engineering tasks with its dedicated Nvidia graphics card and higher RAM. It also boasts a higher resolution touchscreen with higher screen pixel density, and a higher refresh rate. Both laptops have similar battery sizes, but the ASUS has slightly longer battery life. The Lenovo is slightly more portable due to its smaller screen size and lower weight. Both are suitable for intensive gaming but the Lenovo might handle it better thanks to its dedicated GPU.

The Lenovo Slim Pro 9i has a better screen than the ASUS Vivobook S 15 OLED for general use, gaming and AI, engineering and design, content creation, and software development.
For general use and engineering, the ASUS Vivobook S 15 OLED and Lenovo Slim Pro 9i both offer high-resolution, bright OLED displays that provide deep blacks and vibrant colors, beneficial for tasks that require color accuracy like photo editing or design work. However, for gaming and 3D applications, neither of these laptops is ideal due to the lower refresh rates that can lead to less fluid motion and slower response times which are key for an immersive and competitive gaming experience. The Lenovo Slim Pro 9i stands out with slightly superior display technology, offering broader color gamuts and thus even more precise color reproduction for professional-grade engineering and design work.
