The ASUS ZenBook Pro 14 Duo typically costs more than the Lenovo Flex 5 16, but it offers better performance, making it suitable for tasks like 3D rendering or intensive engineering. With higher build quality and heat management, the ASUS is ideal for demanding applications. However, it's heavier and less portable than the Lenovo. On the other hand, the Lenovo offers decent general performance and portability at a lower price. It's a good all-rounder for everyday tasks and some engineering use. If budget allows and performance is a priority, go with ASUS, but for lighter use and travel, consider the Lenovo. Give Feedback

The ASUS ZenBook Pro 14 Duo is very good for general use, while the Lenovo Flex 5 16 is good.
The ASUS ZenBook Pro 14 Duo boasts higher CPU performance, more RAM, and an OLED screen with superior color accuracy, making it very good for general use, yet it has a lower battery life than the Lenovo Flex 5 16, which, despite a less powerful CPU and less RAM, is still considered good for general use thanks to its IPS screen with decent color accuracy and a significantly longer battery life. The ZenBook is less portable due to its weight, while the Flex 5 combines good performance with the added benefit of a 2-in-1 form factor for versatility.

The ASUS ZenBook Pro 14 Duo is very good for engineering and design, while the Lenovo Flex 5 16 is good.
The ASUS ZenBook Pro 14 Duo is likely to outperform the Lenovo Flex 5 16 in engineering and design tasks, as it is equipped with a more powerful CPU, double the RAM, and a high-quality OLED screen that offers better color accuracy and contrast, which is crucial for detailed design work. While both have similar integrated graphics capabilities, the superior screen and hardware of the ASUS make it especially suitable for demanding tasks, though the Lenovo offers greater portability and versatility as a 2-in-1 convertible with a longer battery life and a larger screen.

The ASUS Zenbook Pro 14 Duo has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, engineering and design, software development, and content creation.
When considering screen quality for general use, the ASUS ZenBook Pro 14 Duo's high resolution and brightness, along with an OLED panel, provide crisp and vibrant visuals, while the Lenovo Flex 5 16's slightly lower resolution and brightness still deliver clear and bright images, albeit not as premium. For engineering and design tasks, the ZenBook Pro's wider color gamut coverage ensures more accurate color reproduction, crucial for professional photo editing and graphic design, whereas the Flex's color range is decent but might not satisfy the highest standards of color-sensitive work. However, for gaming and 3D applications, both laptops' screens fall short due to their lower refresh rates, which could lead to less smooth visuals in fast-paced scenes, even though the resolution and panel types are adequate but not optimal for these purposes.

How the ASUS ZenBook Pro 14 Duo and the Lenovo Flex 5 16 compare to other laptops
"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 Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
