The ASUS Zenbook Duo 14 is more portable and offers a touchscreen with better color coverage, making it suitable for general use and good for tasks that benefit from a secondary screen, such as multitasking with creative applications. However, the Lenovo Legion Slim 5, with a higher-refresh-rate display and powerful graphics card, is tailored for gaming and more intensive 3D rendering or machine learning tasks. It also has a larger screen and a higher RAM capacity, which is better for engineering applications. The tradeoff is that the Lenovo is heavier and has lower portability, while the ASUS offers lower performance for heavy-duty tasks but is lighter and has a dual-screen setup for productivity.

"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 Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
