The ASUS ZenBook Pro 14 Duo has superior performance for engineering and 3D/machine learning tasks with more RAM and a higher refresh rate screen, making it more suitable for intensive workloads and viewing fast motion content but has a lower battery life. It's also less portable due to its higher weight and thickness. The Lenovo Flex 5 offers longer battery life and is more portable due to its lighter weight and smaller size, making it a better option for general use and everyday tasks on the go, but it is less powerful for demanding applications like gaming or professional software.

The ASUS Zenbook Pro 14 Duo has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ZenBook Pro 14 Duo likely boasts higher resolution and brightness, along with a superior panel type that enhances the viewing experience for general use and detailed work such as engineering and design, where accurate color reproduction is critical. However, its lower refresh rate may not be ideal for gaming and 3D applications where smoother motion is essential. The Lenovo Flex 5 14 offers adequate resolution and brightness for everyday tasks and casual design work but falls short in both color fidelity for professional design and refresh rate for gaming, making it a balanced, cost-effective option but not exceptional in specific use cases.

How the ASUS ZenBook Pro 14 Duo and the Lenovo Flex 5 14 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 highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
