If you're looking for a balance between price and performance for general use, go with the ASUS Vivobook S 15 OLED; it has a good screen, is less expensive, and is quite portable. However, if you need a laptop primarily for gaming, 3D rendering, or machine learning, the Lenovo Legion 9i is better suited, thanks to its more powerful graphics card and processor, although it's heavier and costs more. The Vivobook may also appeal to those who value longer battery life and a more portable design, while the Legion 9i trades these for superior performance in demanding tasks and a higher-quality build.

The Lenovo Legion 9i is excellent for gaming and AI, while the ASUS Vivobook S 15 OLED is only fair.
The Lenovo Legion 9i outshines the ASUS Vivobook S 15 OLED in gaming and 3D performance due to its more powerful Nvidia RTX 4080 GPU and higher screen refresh rate, vital for smoother visuals and gameplay. Conversely, the ASUS model, while still suitable for gaming with its Intel i9-13900H Iris Xe graphics and decent screen refresh rate, doesn't deliver the same high-end gaming capabilities.

The Lenovo Legion 9i is best in class for engineering and design, while the ASUS Vivobook S 15 OLED is very good.
The Lenovo Legion 9i surpasses the ASUS Vivobook S 15 OLED in power for engineering and design due to its higher RAM capacity, more advanced GPU, and superior CPU, enhancing multitasking and complex graphic computation, with a screen that offers a slightly better resolution and refresh rate. However, the Vivobook's OLED screen provides exceptional color accuracy and contrast which is beneficial for design work, but it is more portable with a lighter build and operates more quietly, which might be favorable for users requiring mobility and a less intrusive device in quiet environments.

The Lenovo Legion 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.
The ASUS Vivobook S 15 OLED boasts a visually detailed and bright display, enhancing daily tasks and professional design work with vibrant colors due to its OLED technology, but lacks the high refresh rate crucial for smooth 3D graphics and gaming experiences. The Lenovo Legion 9i, with its top-tier screen, offers exceptional clarity and color accuracy for both everyday and specialized engineering applications but falls short in providing the high refresh rates preferred by gamers and those working on dynamic 3D projects. While both laptops excel in producing sharp images and covering a wide color spectrum, neither is optimized for gaming or 3D due to their lower refresh rates.

How the ASUS Vivobook S 15 OLED and the Lenovo Legion 9i compare to other laptops
"The Asus Vivobook S 15 OLED excels as a capable work machine at an affordable price. It offers commendable performance, thanks to its 12th Gen Intel chip, delivers quality on-screen entertainment with its 15.6-inch OLED display, and can (kind of) get you through a full day of work. Oh, and its special Asus Antibacterial Guard is a nice touch for those who like a clean laptop."
"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
