The Lenovo Legion 5 15" is good for gaming and AI, while the ASUS Zenbook Duo 14 is only fair.
The Lenovo Legion 5 stands out for gaming and 3D applications owing to its powerful Nvidia RTX 4060 graphics card and a screen that refreshes 165 times per second, while the ASUS Zenbook Duo 14 is limited by its integrated Intel graphics and a less responsive display with a lower refresh rate of 60 times per second. Despite the Zenbook's quality screen and portability, the Legion's superior GPU and higher screen refresh rate make it better suited for high-performance gaming and 3D tasks.

The Lenovo Legion 5 15" is very good for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The Lenovo Legion 5 15" is considered very good for engineering and design due to its more powerful AMD CPU and Nvidia RTX GPU which provide better performance for computation and graphics-oriented tasks, along with a higher resolution screen which is beneficial for design work. Conversely, the ASUS Zenbook Duo 14, while still a solid choice with its Intel CPU and integrated graphics, offers less performance but gains an edge in portability and battery life, making it more suitable for on-the-go users who prioritize a lighter machine and longer usage time.

The Lenovo Legion 5 15" and ASUS Zenbook Duo 14 are both good for general use.
The ASUS Zenbook Duo 14, with its lighter weight and longer battery life, is more portable and offers a dual-screen feature that can be a boon for multitasking in general use, but it has less RAM and a lower powered CPU compared to the Lenovo Legion 5 15", which, despite being less portable due to its heavier build and shorter battery life, has a more powerful CPU and double the RAM, making it better equipped for performance-demanding tasks and thus rated higher for general use. Additionally, the Lenovo Legion 5's higher-resolution display and GPU are more suited to tasks like gaming and media consumption, while its subpar battery life and portability reflect its design as a gaming-oriented machine.

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"The Lenovo Legion 5 15 is an affordable gaming laptop with a lot of power. The new AMD processor Ryzen 7 5800H offers plenty of performance and it is also very efficient. The combination with the fast 130W version of the GeForce RTX 3060 ensures high gaming performance. We also like the fast 165 Hz display with the 1080p resolution. The automatic graphics switching causes some problems with stutters, which are very annoying. If you do not need long battery runtimes, you should definitely deactivate the hybrid graphics mode in Lenovo's Vantage app. The Legion 5 15 is never silent."
