Our Verdict

Lenovo IdeaPad Flex 5i 14 (2022)

Acer Aspire 3 Spin 14 (2023)

The Lenovo IdeaPad Flex 5i 14 (2022) is much better than the Acer Aspire 3 Spin 14 (2023) for most uses. The IdeaPad feels sturdier and provides a better user experience overall, as it has a more spacious and tactile keyboard, a larger touchpad, and a better 1080p webcam. It also has biometrics in the form of a fingerprint sensor and Thunderbolt 4 support, and it's available with significantly faster Intel 12th Gen U-series CPUs.
