If you prioritize performance and features over cost and are looking for a high-resolution, touch-enabled display with more storage and memory, then the Lenovo Slim Pro 9i is a suitable choice; however, its superior specifications also make it more expensive than the Acer Aspire 5 15. The Acer, on the other hand, is more budget-friendly, albeit with less storage, memory, and a standard Full HD display without touch capabilities. If you need long battery life and portability for everyday tasks without the need for intense processing power, the Acer Aspire 5 15 may be the better option. Consider your needs carefully against your budget before making a decision. Give Feedback

The Lenovo Slim Pro 9i is very good for general use, while the Acer Aspire 5 15 is good.
The Lenovo Slim Pro 9i is rated very good for general use largely due to its superior CPU, double the RAM, and a high-resolution Mini LED touchscreen display, which enhances visual quality, while also being lighter with longer battery life for greater portability compared to the Acer Aspire 5 15. Despite this, the Acer Aspire 5 15 is still considered good for general use with a capable processor and sufficient RAM, plus its keyboard and speaker quality are well-regarded, making it a solid choice for everyday tasks.

The Lenovo Slim Pro 9i is very good for engineering and design, while the Acer Aspire 5 15 is only fair.
The Lenovo Slim Pro 9i outshines the Acer Aspire 5 15 for engineering and design primarily due to its superior main processor, double the RAM for multitasking, a more powerful GPU for demanding tasks, and a higher resolution mini-LED screen for superior clarity and color accuracy. Although the Aspire 5 is slightly more portable with a lower weight and promises quieter operation, the Slim Pro 9i offers overall better performance and screen quality which are crucial for engineering and design work.

The Lenovo Slim Pro 9i has a better screen than the Acer Aspire 5 15 for general use, gaming and AI, engineering and design, content creation, and software development.
The Acer Aspire 5 has an adequate display for everyday tasks, but its modest resolution and brightness may not impress users who prioritize sharp, vivid imagery. In contrast, the Lenovo Slim Pro 9i excels in display quality with a high-resolution, bright screen that renders colors accurately, an important aspect for professionals in engineering and design who rely on true-to-life visuals. However, for gaming and 3D applications, both laptops disappoint due to their lower refresh rates, limiting the smoothness and responsiveness crucial for these interactive and fast-paced tasks.

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 Lenovo Slim Pro 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
