If you need a laptop for creative tasks like video editing or design, the ASUS ZenBook Pro 14 Duo with its dual screens can provide a unique multitasking experience, but it may be less convenient to carry around due to its design. The Lenovo Legion Slim 7, on the other hand, is better suited for gaming and possibly offers higher graphics performance along with a larger screen, but this might come at the cost of heavier weight and possibly shorter battery life. Consider how you prioritize mobility, battery longevity, and specific computing needs such as graphics performance or multitasking features when making your choice. Give Feedback

The ASUS ZenBook Pro 14 Duo is very good for general use, while the Lenovo Legion Slim 7 15.6" is good.
The ASUS ZenBook Pro 14 Duo shines in general use due to its high-resolution OLED screen, substantial RAM, and powerful CPU, which deliver a smooth and vibrant user experience; however, its battery life and portability are less favorable compared with the Lenovo Legion Slim 7, which, while also suitable for general use with adequate performance and a quality IPS screen, stands out for its longer battery life and somewhat better portability.

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the ASUS ZenBook Pro 14 Duo is only fair.
The ASUS ZenBook Pro 14 Duo excels in screen quality with its OLED display, providing vibrant colors and contrast, and has a suitable refresh rate of 120Hz for smooth gameplay, though its integrated GPU is not as powerful as dedicated gaming ones. In contrast, the Lenovo Legion Slim 7 has a high-performance Nvidia RTX 3060 GPU and a higher refresh rate of 165Hz for gaming and 3D applications, but its screen, while still of good quality, is standard IPS and not as color-rich as the ASUS.

"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 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."
