If you need a laptop for general use with a focus on long battery life and quiet operation, and are looking at a more budget-friendly option, the Acer Aspire 3 15 is a suitable choice. However, if you require a powerful laptop for tasks like 3D rendering, machine learning, or gaming, and are willing to invest more, the Lenovo Legion Slim 5i would be a better fit due to its higher-end processor, advanced graphics card, and better display. The Legion also has the added benefits of a higher-quality keyboard and more available ports, but keep in mind it is heavier and has a shorter battery life compared to the Acer. Give Feedback

The Lenovo Legion Slim 5i is very good for gaming and AI, while the Acer Aspire 3 15 is poor.
The Lenovo Legion Slim 5i outperforms the Acer Aspire 3 15 in gaming and 3D tasks primarily due to its superior Nvidia RTX 4060 GPU and a higher screen refresh rate, coupled with a robust CPU and higher-quality screen. While the Acer Aspire 3 15 is equipped with a modest AMD Radeon 610M GPU and a standard refresh rate suitable for casual use, its specifications lag behind the Lenovo, making it less ideal for the demands of gaming and 3D applications.

The Lenovo Legion Slim 5i is very good for engineering and design, while the Acer Aspire 3 15 is poor.
The Lenovo Legion Slim 5i has a more powerful CPU and GPU, more RAM, and superior screen quality than the Acer Aspire 3 15, which are all very important for engineering and design tasks, leading to its very good suitability. However, the Aspire might appeal to those prioritizing portability and a quieter device, as it is lighter and offers silent, fanless operation.

"The Acer Aspire 3 is okay for school use. It feels reasonably well-built, and it's easy to carry around. The display looks decently sharp and provides plenty of space for multitasking, but it doesn't get bright enough to combat glare. Its Intel Core i3-N305 CPU and integrated graphics can only handle simple tasks, like text processing, web browsing, and video playback, so it isn't ideal for students in more technical fields like 3D graphics. Unfortunately, the battery lasts only around six to seven hours of light use."

"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
