The ASUS Zenbook Pro 16X offers better performance for intensive tasks like 3D rendering, machine learning, or gaming, due to its powerful processor and high-end graphics card, but it is more expensive and heavier, which may affect portability. On the other hand, the Lenovo Flex 5 16 is more affordable and lighter, making it easier to carry around, but it's less suited for demanding tasks due to its less powerful integrated graphics. For engineering or creative work requiring a high-resolution display, the ASUS might be the better fit with its OLED screen, while the Lenovo is more apt for general use or if budget and portability are key considerations.

The ASUS Zenbook Pro 16X is very good for general use, while the Lenovo Flex 5 16 is good.
The ASUS Zenbook Pro 16X excels in general use due to its high-performance CPU, ample memory, and superior OLED screen quality, providing great visuals and efficient multitasking, but it's heavier and has a shorter battery life compared to the Lenovo Flex 5 16. The Lenovo, while less powerful in processing, offers good general use capabilities with enough RAM, a decent screen, better battery life, and added versatility as a convertible 2-in-1 device, making it easier to carry and use on the go.

The ASUS Zenbook Pro 16X has a better screen than the Lenovo Flex 5 16 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS Zenbook Pro 16X's high resolution and brightness make for a clear and vivid display that's easier on the eyes, while the Lenovo Flex 5 16 offers good quality but may not be as sharp or bright. When it comes to engineering and design tasks, the Zenbook Pro 16X excels with wider color gamuts ensuring more accurate color representation, which is crucial, although the Flex 5 also performs well but isn't as color-accurate. However, for 3D work and gaming, both laptops fall short because of their lower refresh rates, which can lead to less smooth visuals, even though they have decent resolution and panel types for this use case.

"The new Zenbook Pro 16X is more powerful, quieter and doesn't need to shy away from dedicated workstations and gamers. It is also comparatively compact, and our test device is the best Zenbook that we've reviewed so far. It seems equally suitable for content creators and gamers or anyone looking for a very powerful laptop that is still slim."
"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."
