The ASUS Zenbook Duo offers a unique dual-screen setup that could be beneficial for multitasking and certain types of productivity, and it's more portable due to its slightly lighter weight. However, if performance, especially in gaming and engineering applications, is a priority, the Lenovo Legion Slim 7, with its dedicated Nvidia graphics card, will be more capable. This performance advantage might be particularly noticeable in 3D rendering, machine learning, and intensive engineering tasks. The Legion also has a better keyboard, which is an important consideration for long typing sessions. On the other hand, the Zenbook Duo's displays cover a wider color gamut, which could be important for tasks that require color accuracy. If battery life is a concern, the Legion has a slight edge, and it also provides options to expand RAM and storage, increasing its longevity and potential performance over time. Consider how you'll use the laptop: if you value a dual-screen for productivity and a lighter machine, consider the Zenbook Duo; if gaming, engineering, and expandability are your main concerns, the Legion Slim 7 might be the better choice.

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."

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
