When considering the ASUS ZenBook Pro 14 Duo and the Lenovo Legion 9i, think about your priorities. If high performance for tasks like 3D rendering, machine learning, or gaming is crucial and budget is less of a concern, the Lenovo Legion 9i is likely to be the better fit due to its gaming-oriented hardware. However, if you're looking for a more cost-effective option that still performs well for general use and possibly some lighter engineering tasks, the ASUS ZenBook Pro 14 Duo offers savings but with less raw power. The ASUS is also likely to be more portable and potentially have a longer battery life, which is advantageous if you travel frequently or work on the go. Keep in mind that with the lower price of the ASUS, you may compromise on the maximum capabilities that the Lenovo offers, especially in demanding applications. Give Feedback

The ASUS ZenBook Pro 14 Duo and Lenovo Legion 9i are both very good for general use.
The ASUS ZenBook Pro 14 Duo is highly suitable for general use thanks to its solid CPU and ample RAM that ensure smooth multitasking, paired with an OLED screen that provides excellent color accuracy and contrast for a vivid display; its relatively lighter weight and reasonably good battery life offer easier portability for everyday tasks. On the other hand, the Lenovo Legion 9i also shines in general use with a more powerful CPU and the same amount of RAM for demanding applications, complemented by its Mini LED screen with higher brightness and refresh rate for sharp and smooth visuals; though it offers better speaker and keyboard quality, this comes at the cost of reduced portability due to its heavier build and lower battery life.

"The Zenbook Pro 14 Duo OLED is a well-tuned instrument for content creators, excelling at a range of general office tasks as well as tasks that require a little more grunt like encoding and 3D rendering. The big attraction is the laptop’s dual displays. They’re the best ones we’ve used in an Asus Zenbook Duo laptop to date with a spate of year-on-year improvements that make the visuals more striking and the cross-screen integration easier than ever before."

"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."
