If you prioritize high performance for tasks like 3D work, machine learning, or gaming, and are willing to invest more, the Asus ZenBook Pro 14 Duo may be a better choice despite its higher cost. However, if you are looking for a laptop that is more budget-friendly and offers satisfactory performance for general use like web browsing, office applications, and media consumption, the Lenovo IdeaPad Slim 3 would be sufficient. The ZenBook also usually offers better build quality and advanced features but may be less portable due to its weight and size compared to the lighter and more compact IdeaPad Slim 3. If battery life is crucial for you, the IdeaPad Slim 3 might have the edge, especially if the laptop will often be used on the go. Give Feedback

The ASUS ZenBook Pro 14 Duo is very good for general use, while the Lenovo IdeaPad Slim 3 is good.
The ASUS ZenBook Pro 14 Duo offers superior performance for general use due to its more powerful CPU, significantly greater RAM, and higher-quality OLED screen, though it is less portable and has a shorter battery life compared to the Lenovo IdeaPad Slim 3. While the IdeaPad Slim 3 is easier to carry around and offers longer battery usage, its capabilities are more modest with a basic CPU, less RAM, and an IPS display that doesn't match the vividness or sharpness of the ASUS's OLED panel.

The ASUS Zenbook Pro 14 Duo has a better screen than the Lenovo IdeaPad Slim 3 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro 14 Duo boasts a high-resolution display and superior brightness alongside wide color gamuts, making vibrant and clear visuals ideal for engineering and design tasks, but its standard refresh rate limits its performance for gaming where smooth motion is key. Conversely, the Lenovo IdeaPad Slim 3's fair display, with adequate resolution and brightness, offers a satisfactory experience for everyday activities and basic design work, though it lacks the color range that professionals may seek and doesn't cater to the high refresh rate needed for 3D applications and gaming. Therefore, while the ASUS excels in visual fidelity for professional creative work, its gaming capabilities are hampered by refresh rate limitations, and the Lenovo, while serviceable for general tasks, doesn't stand out in any specific area.

"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 IdeaPad 3i is decent for use as a workstation. Its Intel CPU and integrated graphics can only handle light productivity tasks, not demanding workloads like video editing or 3D graphics. You also can't do any color-critical work because the available displays have a narrow color gamut. It has a good port selection, but its USB-C lacks Thunderbolt 4 support. On the upside, it has a comfortable keyboard and doesn't get hot or loud under load."
