The Acer Aspire 3 14 is a budget-friendly option that may cost significantly less and could be suitable for general use with moderate battery life, but it has less storage and memory than the Lenovo Flex 5 14. The Flex 5, while more expensive, offers double the storage and memory, a better processor, and a touch screen with a slightly higher resolution, which could enhance its performance for engineering tasks, 3D rendering, and machine learning. It also boasts a better battery life. If portability is a concern, both laptops are similar in size and weight, although the Flex 5 is slightly heavier. Consider the Acer Aspire 3 if you're looking for a more budget-conscious option for everyday tasks, whereas the Lenovo Flex 5 might be the better choice if you're willing to invest more for improved performance in more demanding applications.

The Lenovo Flex 5 14 has a better screen than the Acer Aspire 3 14 for general use, engineering and design, content creation, and software development.
The Acer Aspire 3 and Lenovo Flex 5 both offer screen qualities that are sufficient for typical tasks such as browsing the web and office work, due to their adequate resolution and brightness; however, professionals who require precise color representation for engineering and design may find them lacking in the breadth of color gamuts. Gamers, on the other hand, will not find these models optimal, as their screens offer lower refresh rates which are not ideal for the fast-paced visuals in gaming and 3D applications. While both models balance general use needs, neither is optimized for the specialized demands of engineering and gaming enthusiasts.

Allen Ngo | May 2021
"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."
