If price is a significant concern, and your needs are more towards general use with moderate performance for tasks like web browsing, standard office applications, and video streaming, the ASUS Vivobook 15X may be better as it's less expensive. However, it has less storage, lower RAM, and a processor and graphics that are suitable for general tasks but not high-performance gaming or intensive engineering applications. In contrast, the Lenovo Legion 9i is a high-performance laptop with significantly more storage, RAM, a powerful processor, and an advanced graphics card that make it excellent for gaming, 3D rendering, machine learning, and demanding software used in engineering. The tradeoff here is that it's much more expensive, and it's also heavier, which might affect its portability. Additionally, the Legion 9i has superior screen quality, offering a higher resolution and better color accuracy, which can be important for creative professionals or those who desire a more immersive gaming experience. The Legion 9i is also better equipped for connectivity, with more ports, including Thunderbolt. If budget allows and performance is critical, especially for demanding tasks, the Lenovo Legion 9i may be the better choice. However, for everyday use where portability with reasonable performance is desired, the ASUS Vivobook 15X could be more appropriate. Give Feedback

The Lenovo Legion 9i has a better screen than the ASUS Vivobook 15X for general use, gaming and AI, engineering and design, content creation, and software development.
The ASUS Vivobook 15X has a screen that's adequate for everyday tasks due to its resolution and brightness, but for engineering and design, the color accuracy isn't top-notch, and for gaming or 3D applications, it falls short due to a lower refresh rate.

"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."

Matthew Buzzi | December 2023
"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."
