The Lenovo Flex 5 16 and Acer Aspire 5 17 are both good for general use.
The Acer Aspire 5 17 offers a generous 17.3-inch screen paired with an Intel i5 processor and 8GB RAM, providing smooth performance for everyday tasks, yet its larger size and average battery life make it less portable than some alternatives. On the other hand, the Lenovo Flex 5 16 not only has a higher-resolution screen and double the RAM for more demanding multitasking, but also better battery life and the versatility of a 2-in-1 design, though with slightly less portability due to its design and screen size.

The Lenovo Flex 5 16 and Acer Aspire 5 17 are both only fair for gaming and AI.
The Acer Aspire 5 17 and Lenovo Flex 5 16 are suitable for casual gaming and 3D tasks due to their comparable integrated Iris Xe graphics, but neither is equipped with dedicated gaming GPUs or high screen refresh rates, which are crucial for demanding gaming performance. While both have IPS screens with a standard 60Hz refresh rate, the Lenovo Flex 5 16 possesses a higher screen resolution and quality which may offer slightly better visual detail for games and 3D applications.

Although they have very similar scores, PerfectRec considers Lenovo Flex 5 16 to be good for engineering and design, while the Acer Aspire 5 17 is only fair.
The Acer Aspire 5 17's performance in engineering and design tasks is fair owing to its lesser RAM and a lower-end CPU compared to the Lenovo Flex 5 16, which is equipped with more RAM and a higher-tier CPU for better multitasking and computational power; additionally, the Flex has a higher-quality screen with better color coverage, enhancing visual design work. Despite these advantages, the Aspire 5 may be preferred for its larger screen size though it may sacrifice some portability and display quality compared to the Flex, which balances performance, screen quality, and portability.

Marcus Schwarten | March 2021
"The Acer Aspire 5 17 laptop shows the expected strengths in the test. Besides the usual high build quality, the configuration convinces in most benchmarks and tests. The combination of CPU, GPU, and RAM is absolutely sufficient for the everyday office and browsing tasks of a laptop. It also renders the odd game passably if the requirements aren't too high. We liked the matte display in the test as well as the fairly manageable dimensions despite the screen size. It can also be used outdoors, even if it's certainly not a laptop designed for mobility."

"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."
