If you prioritize a touch screen and higher resolution, the Lenovo Flex 5 16 is a better choice; it also offers double the RAM, which helps with multitasking and more intensive tasks. It further boasts a slightly larger battery and a backlit keyboard with a number pad, useful for productivity. However, it's heavier and more costly than the Acer Aspire 3 14. The Acer has the advantage of being more portable and budget-friendly, with lesser but adequate performance for general use, and a quieter operation without a fan. Neither is ideal for intensive gaming though. Give Feedback

Andreas Osthoff | April 2023
"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."
