For general use and portability, the Acer Aspire Go 15 is a solid choice with its lightweight design and sufficient performance for everyday tasks, though it falls short in gaming and intensive applications due to its basic processor and lack of a dedicated GPU. The Lenovo Flex 5 16, on the other hand, offers a more powerful processor and a high-resolution touchscreen display with better color accuracy, making it suitable for more demanding tasks and better overall performance. However, it's heavier and has a shorter battery life compared to the Acer. If you need a versatile device for both work and entertainment, and you're okay with a bit less portability, the Lenovo Flex 5 16 would be the better option. 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."
