The ASUS ZenBook Pro 14 Duo is very good for general use, while the Lenovo Legion Slim 5i is good.
The ASUS ZenBook Pro 14 Duo stands out for general use due to its high-quality CPU and RAM, combined with an excellent screen and portability, despite having less battery life compared to the Lenovo Legion Slim 5i, which offers good general performance with a focus on CPU and portability but sacrifices screen quality and has a lesser quality RAM. Both laptops manage heat well and offer decent storage, keyboards, speakers, and operating noise, but the ASUS's better overall balance of very important features makes it more suitable for a wide range of tasks.

The Lenovo Legion Slim 5i is very good for gaming and AI, while the ASUS ZenBook Pro 14 Duo is only fair.
The Lenovo Legion Slim 5i is rated higher for gaming and 3D applications primarily because it has a more powerful Nvidia RTX 4060 GPU and a higher screen refresh rate of 165Hz, compared to the ASUS ZenBook Pro 14 Duo which uses a less powerful Intel i7-12700H Iris Xe graphics and has a lower refresh rate of 120Hz. Even though processing power and screen quality are somewhat important, the Legion Slim 5i's superior GPU and refresh rate provide a significant advantage for gaming and 3D tasks.

"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 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."
