If the lower price is a priority and you need a reliable laptop for general use, the Acer Aspire might suit you well, as it often costs less. However, if you require a larger screen and the versatility of a 2-in-1 laptop that can also be used as a tablet with a touchscreen interface, the Lenovo Flex with its bigger display might be worth the extra investment. Keep in mind that the larger screen and 2-in-1 functionality could mean a trade-off with portability and battery life compared to the typically more compact and efficient Acer Aspire. For tasks like 3D work, machine learning, gaming, or engineering, make sure to compare the specific hardware like processors, graphics cards, and memory, as these will significantly impact performance in those areas.

The Lenovo Flex 5 16 is good for engineering and design, while the Acer Aspire 5 15 is only fair.
The Acer Aspire 5 15 is suitable for engineering and design due to its capable processor, sufficient RAM for multitasking, integrated graphics good enough for less demanding design applications, and a full HD screen providing clarity for detailed work. The Lenovo Flex 5 16, on the other hand, offers a more powerful processor, the same amount of RAM, an identical integrated graphics capability, and a sharper, higher resolution display that can enhance design precision, along with the advantage of being a convertible 2-in-1 device, making it versatile for various modes of usage.

The Lenovo Flex 5 16 has a better screen than the Acer Aspire 5 15 for general use, gaming and AI, engineering and design, and software development.
When considering the Acer Aspire 5 15 and the Lenovo Flex 5 16 for general use, the Lenovo likely offers a brighter and crisper display due to its resolution and panel quality, making it easier on the eyes during day-to-day tasks. For engineering and design work, the color accuracy is crucial, and the Lenovo Flex 5 16 might provide a wider color gamut, rendering more precise and vibrant colors necessary for detailed projects. However, for gaming and 3D applications, despite neither laptop having an ideal high refresh rate, the panel type and resolution on both models may only provide a basic experience; therefore, dedicated gaming laptops would be more suitable for these purposes.

The Lenovo Flex 5 16 and Acer Aspire 5 15 are both only fair for gaming and AI.
The Acer Aspire 5 15 has an Intel Iris Xe GPU which is suitable for casual gaming, though it may not handle high-end games well due to its lower tier processor and standard 60Hz refresh rate. In contrast, the Lenovo Flex 5 16 also features an Intel Iris Xe GPU, but with a slightly better processor, and its higher resolution display might offer better image quality for games, despite also having a standard refresh rate which is not ideal for fast-paced gaming.

"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."

Andreas Osthoff | April 2023
"The Lenovo IdeaPad Flex 5 is a solidly equipped, 2-in-1 in the lower price segment. Performance is definitely sufficient for everyday tasks and in tests the battery proved itself to be very economical. That aside, there is a lot of standard fare on show and a search for real highlights ends in vain. The low color coverage and reflective display can be avoided by going for an optional 2.5K display but this also presumably results in poorer battery life. The cooling uses only one fan and leads to a raised temperature on one side of the device under load. Additionally, there is very loud fan noise, also under load or when gaming. On top of that, we also occasionally noticed electronic noises."
