If price is a major concern, the Acer Aspire 3 15 is the less expensive choice while still offering good features for general use, including a full-sized keyboard with a numeric pad, which might be useful for data entry and productivity tasks. However, the Lenovo Flex 5 14, although more pricey, provides higher overall performance, which could be beneficial for more intense tasks like engineering software, 3D rendering, or machine learning, and it comes with a touchscreen and a more portable design that may suit those on the go. The Flex 5 also has a longer battery life and greater storage space, which are advantages for users with more demanding software and storage needs. Give Feedback

The Lenovo Flex 5 14 has a better screen than the Acer Aspire 3 15 for general use, content creation, and software development.
For general use, both the Acer Aspire 3 and Lenovo Flex 5 offer screens with adequate resolution and brightness, but they may not have the premium panel types that provide the most vibrant colors and viewing angles. In engineering and design, where color accuracy is crucial, these laptops have fair screen quality because they cover only a basic range of color gamuts, lacking the full spectrum needed for professional color work. Additionally, for 3D and gaming, the lower refresh rates on these laptops' screens mean less fluid motion and slower responsiveness, though the resolution and panel type are acceptable for casual use.

Although they have very similar scores, PerfectRec considers Lenovo Flex 5 14 to be only fair for gaming and AI, while the Acer Aspire 3 15 is poor.
The Acer Aspire 3 15 is suited for fair-level gaming and 3D tasks primarily because it has an AMD Radeon 610M GPU and a 60Hz screen refresh rate, which are basic for gaming but may not handle more demanding games and high-detail 3D applications very well.

"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 highlight of the latest IdeaPad Flex 5 14 is clearly its AMD CPU. The octa-core Ryzen 7 5700U is insanely fast even when compared to the best Tiger Lake Ultrabooks in the market or even Core H CPUs in many gaming laptops. It's a lot of raw processing power for what is supposed to be a budget 14-inch convertible. If your daily workloads can benefit from extra multi-thread CPU performance, then look no further than the inexpensive AMD-powered Lenovo IdeaPad Flex 5 14. For regular on-the-road browsing or video streaming, however, a slimmer and lighter 10th gen Core Yoga, Spectre, or XPS would be a more balanced option."
