The Acer Aspire 5 15 typically costs less than the Lenovo IdeaPad Slim 5i, so if you're on a tighter budget, that might be the way to go. However, if you can stretch your budget a bit, the Lenovo IdeaPad Slim 5i offers a slightly better battery life and a higher resolution screen with a taller aspect ratio, which could be beneficial for productivity tasks like reading and writing documents. Both have the same processor and RAM, so general performance should be similar. The Lenovo also has a slightly higher weight, so if portability is a major factor for you, the Acer might be preferable. Keep in mind the higher price of the Lenovo might also get you better build quality and possibly a more premium feel. Give Feedback

The Lenovo IdeaPad Slim 5i has a better screen than the Acer Aspire 5 15 for general use, and engineering and design.
If you primarily use your laptop for everyday tasks like browsing, document editing, and video streaming, both the Acer Aspire 5 15 and Lenovo IdeaPad Slim 5i offer adequate screen quality, but they won't stand out in terms of resolution and brightness. For those working in engineering and design fields, where color accuracy is crucial, both models provide fair performance, yet they lack the wide color gamuts needed for the most professional work. Gamers and 3D artists seeking fluid motion and detailed visuals will find both laptops fall short, as they do not have the high refresh rates and only moderate resolution and panel quality required for optimal viewing experiences.

Sascha Mölck | November 2022
"The Acer Aspire 5 15 is a good value office laptop with reasonable battery life. The combination of slim exterior, relatively low weight (approx. 1.7 kg) and 8 hour real-life battery runtime makes the Acer Aspire a truly mobile laptop. The modest Tiger Lake processor supports this area and simultaneously ensures an affordable price point. The Aspire produces little noise and stays cool. The screen (FHD, IPS) might not win any prizes but is entirely appropriate for the price."

"The device is made for average work loads and if your work has a lot to do with online browsing, using apps that are not power-hungry and streaming videos. The looks are really good and the device in itself is not a heavy one. And with Intel 11th-gen Core processor, you might sail through most of your work without complaints."
