The ASUS Vivobook Go 15 is significantly less expensive, more portable due to its lighter weight, and has a longer battery life, which is suitable for everyday tasks and general use. However, the Lenovo Legion 9i, although more expensive, offers superior performance with a much more powerful processor and graphics card, making it ideal for intensive gaming, 3D rendering, and engineering tasks. The Legion 9i also features a higher-quality screen with better resolution, color accuracy, and a higher refresh rate which is ideal for creative professionals. If budget is a constraint or you need a lightweight laptop for basic tasks, the ASUS is a practical option; conversely, the Lenovo is better if performance and a high-quality display are priorities and you're willing to invest more.

The Lenovo Legion 9i is very good for general use, while the ASUS Vivobook Go 15 is poor.
The ASUS Vivobook Go 15, with modest CPU performance, limited RAM, and lower-tier screen quality, compromises on speed and visual clarity, impacting its effectiveness for general use. In contrast, the Lenovo Legion 9i's advanced CPU, ample RAM, and superior screen provide a smooth and vivid experience essential for demanding tasks and entertainment, though its portability and battery life are less favorable than lighter laptops designed for more casual use.

The Lenovo Legion 9i is best in class for engineering and design, while the ASUS Vivobook Go 15 is poor.
The ASUS Vivobook Go 15 has a basic Intel Celeron processor, minimal RAM, and a basic integrated GPU, making it unsuitable for the demanding CPU, RAM, and GPU requirements of engineering and design tasks, whereas the Lenovo Legion 9i comes with a powerful Intel i9 processor, abundant RAM, and a high-end Nvidia GPU that excel at such tasks. Additionally, the screen quality of the Legion 9i is superior, with a higher resolution and better color accuracy, whereas the Vivobook has a lower-quality TN panel with limited color coverage and brightness, affecting the visual precision necessary for engineering and design work.

The Lenovo Legion 9i has a better screen than the ASUS Vivobook Go 15 for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS Vivobook Go 15 may have a lower resolution, dimmer display which affects the quality for general tasks, and lacks the color accuracy and gamut range needed for engineering and design work. The Lenovo Legion 9i offers a superior display with higher brightness, resolution, and more accurate color coverage, optimal for tasks in general use and engineering, but its lower refresh rate hampers performance in fast-paced 3D environments where smoothness is key. For gaming and 3D modeling, the need for high refresh rates is crucial, hence the Legion 9i might not be the best fit despite its superior resolution and panel type.

"The Asus Vivobook Go 15 is a good option if you’re looking for one device to tackle a bunch of smaller problems. For simple school studies, portable evening entertainment or distractions, and getting household admin or light office workloads out of the way, it’s a great little package with respectable battery life, and a great contender for the advent of cloud gaming."
"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."
