The ASUS Zenbook 13 and the Lenovo Legion 9i cater to different needs. If you prioritize a lightweight, portable device with good battery life and a vivid OLED display for day-to-day tasks, and at a lower price, then the ASUS Zenbook 13 is a good choice. However, if your work includes intensive engineering tasks, 3D rendering or machine learning, and you need top-of-the-line performance and are willing to invest in a higher-priced laptop, the Lenovo Legion 9i with its powerful Intel processor and RTX 4080 graphics card would be more appropriate, despite being heavier and having shorter battery life.

The Lenovo Legion 9i is very good for general use, while the ASUS Zenbook 13 is good.
The ASUS Zenbook 13 is well-suited for general use due to its lightweight design and solid battery life, but its lower RAM and CPU capabilities may limit performance compared to the Lenovo Legion 9i, which excels with a more powerful CPU, more RAM, and a higher quality screen, though it is less portable and has a shorter battery life. While the Zenbook 13 offers portability and sufficient power for everyday tasks, the Legion 9i is better equipped for demanding applications and provides a superior audio-visual experience, but its heavyweight and lower portability make it less ideal for frequent travel.

Sebastian Bade | May 2021
"The Asus ZenBook 13 is a compact 13-inch laptop with a fast Ryzen 7 5800U and OLED display. The subnotebook is also light and the modern design is convincing. The selection of high-quality materials make the device not only light, but also very stable. In addition, the visuals and haptics of the device offers a high-quality impression. The AMD Ryzen 7 5800U is a very good fit for the ZenBook 13, ensuring a high performance in the test. However, in terms of the 3D performance, we also notice that the Vega architecture is beginning to hit its limits."

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."
