If portability and battery life are crucial for you, then the ASUS Zenbook 13, with its lighter weight and longer battery life, is a good choice, especially if you're frequently on the move. However, the Lenovo Flex 5 14 offers a touchscreen, more storage, and additional RAM, which makes it better suited for heavy multitasking and tasks that benefit from a touchscreen interface. Both laptops are similarly priced and have comparable high-quality keyboards, but if your work involves color-sensitive tasks, you might prefer the ASUS with its OLED display. Neither is ideal for intensive gaming, but for general use, both will serve well. Choose the Lenovo if you need more power and versatility with a small sacrifice in portability and battery life.

The ASUS Zenbook 13 has a better screen than the Lenovo Flex 5 14 for general use, gaming and AI, and engineering and design.
The ASUS Zenbook 13 offers high resolution and brightness, making it great for general use and detailed engineering tasks, as these aspects ensure crisp text and vivid imagery, while a wide color gamut supports accurate color work in design. However, it lacks a high refresh rate, which is crucial for smooth visuals in gaming and 3D applications, leading to its poorer performance in those areas. The Lenovo Flex 5, while providing adequate resolution and brightness for everyday tasks and some engineering work, offers neither the superior color range needed by professionals in design nor the high refresh rate sought after by gamers, leading to its fair assessment in these categories.

The Lenovo Flex 5 14 and ASUS Zenbook 13 are both good for general use.
The ASUS Zenbook 13 offers an OLED screen with vibrant colors, a lightweight build for better portability, and stands out due to its higher screen brightness and contrast, which makes for a sharper and more enjoyable viewing experience, but it has less RAM and storage compared to the Lenovo Flex 5 14.

The Lenovo Flex 5 14 and ASUS Zenbook 13 are both only fair for gaming and AI.
The ASUS Zenbook 13 with its AMD Ryzen 7 and integrated Vega 8 graphics paired with an OLED screen offers decent capabilities for gaming and 3D work, although its 60Hz refresh rate is a standard that may limit smooth visuals in fast-paced scenes. In comparison, the Lenovo Flex 5 14 also features the same level of graphics capabilities with an AMD Ryzen 7 and integrated Vega 8 graphics, but it offers a slightly higher resolution IPS display, which does not quite match the visual quality of OLED but could still provide satisfactory gaming and 3D experiences for casual users.

The ASUS Zenbook 13 and Lenovo Flex 5 14 are both good for engineering and design.
The Lenovo Flex 5 14 outperforms the ASUS Zenbook 13 in engineering and design usage largely due to its higher RAM capacity,-touch-screen display with a higher resolution and aspect ratio, and a more recent CPU, which collectively provide smoother multitasking and a more robust workspace for design applications. Conversely, the Zenbook's advantages, such as its high-contrast OLED screen and lighter weight, may benefit general use and media consumption, but fall short for extensive engineering tasks where RAM and CPU capabilities are prioritized over display and portability.

"The Asus ZenBook 13 is a compact 13-inch laptop with a fast Ryzen 7 5800U and OLED display. The subnotebook is also light and the modern design is convincing. The selection of high-quality materials make the device not only light, but also very stable. In addition, the visuals and haptics of the device offers a high-quality impression. The AMD Ryzen 7 5800U is a very good fit for the ZenBook 13, ensuring a high performance in the test. However, in terms of the 3D performance, we also notice that the Vega architecture is beginning to hit its limits."

"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."
