If you prioritize a larger screen and don't mind a heavier laptop, the Acer Aspire 5 17 with its 17.3-inch display could be suitable; however, it offers lower storage compared to the Lenovo. On the other hand, the Lenovo Flex 5 14 is more portable due to its smaller size and lighter weight, and it also features a touchscreen, which the Acer lacks. The Lenovo might be slightly more expensive, but it comes with double the storage and higher RAM, enhancing its performance for multitasking and demanding applications. Both laptops are similar in battery life and offer backlit keyboards, but the Lenovo also has a fingerprint reader for additional security. Give Feedback

The Lenovo Flex 5 14 has a better screen than the Acer Aspire 5 17 for general use, engineering and design, content creation, and software development.
If you're using the laptop for everyday tasks like browsing and watching videos, the Acer Aspire 5 and Lenovo Flex 5 both have suitable screens, but they may not be very vibrant or exceptionally sharp due to average resolution and brightness. For engineering and design work, where accurate color representation is crucial, both laptops may fall short as they likely don't cover the wider color gamuts preferred for professional editing and rendering. Gamers and those into 3D work will find both laptops lacking, as they do not have the high refresh rates required for smooth visuals and may not have the resolution to make the most detailed graphics pop.

The Lenovo Flex 5 14 and Acer Aspire 5 17 are both only fair for gaming and AI.
The Acer Aspire 5 17 and Lenovo Flex 5 14 are rated similarly for gaming and 3D because they both have integrated graphics that perform modestly in such tasks — the Acer with an Iris Xe and the Lenovo with a Vega 8. Both laptops also have IPS screens with standard refresh rates which suffice for casual gaming, but may not satisfy users looking for a premium gaming experience.

Although they have very similar scores, PerfectRec considers Lenovo Flex 5 14 to be good for engineering and design, while the Acer Aspire 5 17 is only fair.
The Acer Aspire 5 17 is equipped with an Intel CPU and Iris Xe graphics, but the Lenovo Flex 5 14 offers a more powerful AMD Ryzen CPU and Vega 8 graphics, which can handle engineering and design tasks more proficiently. Additionally, the Lenovo has twice the RAM of the Acer and offers a higher resolution and touchscreen display, which contributes to better overall performance and screen quality for design work.

Marcus Schwarten | March 2021
"The Acer Aspire 5 17 laptop shows the expected strengths in the test. Besides the usual high build quality, the configuration convinces in most benchmarks and tests. The combination of CPU, GPU, and RAM is absolutely sufficient for the everyday office and browsing tasks of a laptop. It also renders the odd game passably if the requirements aren't too high. We liked the matte display in the test as well as the fairly manageable dimensions despite the screen size. It can also be used outdoors, even if it's certainly not a laptop designed for mobility."

"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."
