Considering the ASUS Zenbook Duo has a dual-screen design, it's ideal if you value multitasking on additional displays and prefer a touch screen. The laptop is lighter, enhancing its portability, but has half the storage of the Lenovo. It also has a slightly better battery life for typical use. The Lenovo Legion Slim 5i, while heavier and thicker, offers more storage and a powerful dedicated graphics card, making it better suited for gaming, 3D modeling, and engineering tasks. Its keyboard and webcam are rated higher, so if you often type or video conference, it might be more comfortable over long periods. If gaming and higher performance are priorities, and you don't mind a bit more weight, the Lenovo is the stronger choice; if portability and a unique dual-screen setup are more important, go for the ASUS.

How the ASUS Zenbook Duo (2024) and the Lenovo Legion Slim 5i compare to other laptops
"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."
