If performance for intensive tasks like engineering or gaming is a priority, the ASUS Vivobook 16X with its more powerful processor and dedicated graphics card is a superior choice. However, it's slightly less portable and has shorter battery life compared to the Lenovo Flex 5 16. The Flex 5, featuring a touchscreen and higher resolution display, may offer a better experience for general use and media consumption, and it's lighter with longer battery life, making it more suitable for on-the-go use. If cost is a concern, the Flex 5 typically comes at a slightly lower price point. Give Feedback

Kok Kee | February 2023
"I think the ASUS Vivobook 16X is fantastic. Great performance, decent battery life, good keyboard and trackpad, and a massive screen – just that the screen quality itself is kinda subpar. If you’re okay with the screen, then I think this is an okay laptop. However, I’d like to see a price drop."

"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."
