The ASUS Vivobook 15X is slightly more affordable and could be a good fit if you prioritize a larger 15.6-inch screen for activities like multitasking or entertainment. However, its performance is not as strong as the Lenovo Flex 5 14, which boasts a more powerful processor and double the memory, making it better for demanding tasks like engineering software, 3D modeling, or heavier multitasking. The Lenovo also features a higher-resolution touch display in a 14-inch size, which supports stylus input, and it's a 2-in-1 convertible capable of being used as a tablet. If portability and flexibility are key for you, the Lenovo Flex 5 14 is also slightly lighter. In terms of battery life, the Lenovo has a slightly larger battery, which could translate to longer usage times depending on your tasks. Therefore, for those who need a machine capable of handling more intensive tasks and value versatility, the added cost of the Lenovo may be justified, while for those who favor larger screens and lower costs, the ASUS might be the better option despite its lower performance capabilities.

The Lenovo Flex 5 14 has a better screen than the ASUS Vivobook 15X for general use, content creation, and software development.
For general use, the Vivobook 15X and Flex 5 14 offer screens with adequate resolution and brightness, making them satisfactory for daily tasks like browsing and video streaming, despite not having the premium panel types that would provide superior viewing angles and color reproduction. When it comes to engineering and design, both laptops have fair color accuracy, but they lack the wide color gamuts needed for high-level professional work that demands precise color matching. As for gaming and 3D applications, the refresh rates on these laptops are not high enough to provide the smooth visuals necessary for high-speed gaming or advanced 3D rendering, and while their resolutions are acceptable, they don't offer the quickest response times for fast-paced interactive experiences.

"All in all, my day on the Vivobook had its ups and downs. It is a really pretty and well-built device, and it had all of the functionality I needed to get me through my browser-based workload. But the speakers weren’t my favorite, and the battery life was just too short."

"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."
