The ASUS Zenbook Pro 15 is more affordable and offers a high-resolution OLED touchscreen which is great for vibrant colors and contrast, making it suitable for everyday use and multimedia tasks, and it also has longer battery life for on-the-go work. However, the Lenovo Legion 9i has a more powerful processor and graphics card, more RAM and storage, and a high-refresh-rate Mini LED display, which excels in intensive gaming, 3D rendering, machine learning, and demanding engineering software, but is heavier and has a shorter battery life, making it less portable. Both have backlit keyboards, but the Lenovo's is RGB, implying a focus on gaming aesthetics. Give Feedback

"The ASUS Zenbook Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."

"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."
