If you seek portability and longer battery life for general use like web browsing or office tasks, the Lenovo Flex 5 14 is the more suitable option due to its lighter weight and longer typical usage battery life. However, if your activities involve engineering applications, 3D rendering, gaming, or machine learning, the Lenovo Legion 5 17" would be a better fit as it has a more powerful graphics card and higher performance scores in these areas, but it's heavier and has a shorter battery life which affects portability. The Flex has a touchscreen with a higher resolution and aspect ratio, which is great for productivity and media consumption, while the Legion offers a higher refresh rate screen for smoother visuals in fast-paced games.

The Lenovo Flex 5 14 has a better screen than the Lenovo Legion 5 17" for software development, and content creation, while the Lenovo Legion 5 17" has a better screen for general use, gaming and AI, and engineering and design.
The Lenovo Flex 5 14, with moderate resolution and brightness, offers adequate visuals for everyday tasks and productivity, but its color coverage may not satisfy engineering and design professionals needing precision. In contrast, the Lenovo Legion 5 17" has a larger, brighter display with better resolution, which benefits both general and technical applications, though its color gamut may still fall short for high-end design work. Neither laptop is ideal for 3D gaming due to lower refresh rates, which compromises the smoothness and responsiveness critical in that space.

How the Lenovo Flex 5 14 and the Lenovo Legion 5 17" compare to other laptops
"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."
"The Lenovo Legion 5 17 is a current-gen 17-inch gaming laptop and equipped with the latest AMD CPU and a powerful GPU, that manages to reach its full potential. The AMD Ryzen 5 5600H is a very good choice for this laptop and able to maintain its performance level for long periods of time. Our test model only falls behind consistently in a direct comparison with its competitors that are often equipped with eight cores and 16 threads. Despite this, the Legion 5 17 leaves an excellent impression and is almost able to keep up with an Nvidia GeForce RTX 3070 mobile GPU in synthetic benchmarks."
