Our Verdict
Lenovo IdeaPad Slim 3i 15 (2023)
Acer Aspire 5 15 (2023)
The Acer Aspire 5 15 (2023) and the Lenovo IdeaPad Slim 3i 15 (2023) are both 15-inch budget laptops. The Lenovo provides a better user experience, sporting a more tactile keyboard, a more responsive touchpad, and a better webcam. However, you can get more performance out of the Acer because it's available with faster H-series CPUs. The Acer also has better battery life, lasting almost two hours longer than the Lenovo.
