Our Verdict
Lenovo IdeaPad Slim 3i 15 (2023)
Acer Aspire 15 (2024)
The Acer Aspire 15 (2024) and the Lenovo IdeaPad Slim 3i 15 (2023) are very similar overall. The Lenovo has a slightly more tactile keyboard, and its touchpad is more responsive to some actions like dragging and dropping. However, the Acer is available with newer, faster Intel Raptor Lake CPUs, so it can handle heavier multitasking and more demanding applications.
