The Acer Aspire 3 14 is a budget-friendly option, with sufficient power for everyday tasks and a reasonable battery life, making it suitable for general use and light productivity. Its portability is enhanced by its lighter weight compared to the Lenovo Legion Slim 7 15.6, which offers higher performance for engineering, 3D rendering, and machine learning, benefiting from a more powerful processor, graphics card, and additional memory. However, the Lenovo is heavier and typically more expensive, making it less ideal for frequent travel but more fitting for demanding applications and gaming. Give Feedback

The Lenovo Legion Slim 7 15.6" and Acer Aspire 3 14 are both good for general use, though the Lenovo Legion Slim 7 15.6" is somewhat better.
The Acer Aspire 3 14 is fair for general use because it offers a modest AMD Ryzen 5 CPU, 8GB of RAM, and a basic screen with lower brightness and color coverage, which, however, contributes to its lighter weight and longer battery life, helping with portability.

The Lenovo Legion Slim 7 15.6" is good for gaming and AI, while the Acer Aspire 3 14 is poor.
The Acer Aspire 3 14 is considered fair for gaming and 3D largely due to its modest GPU and standard screen refresh rate, which are less suitable for demanding graphics and fast-paced action. In contrast, the Lenovo Legion Slim 7 15.6" is rated good for these tasks because of its robust GPU and high screen refresh rate, which allow better performance and smoother visuals in graphic-intensive games and 3D applications.

The Lenovo Legion Slim 7 has a better screen than the Acer Aspire 3 14 for general use, gaming and AI, engineering and design, content creation, and software development.
The Acer Aspire 3's screen offers enough resolution and brightness for typical tasks like browsing and document editing, but its color range falls short for color-critical work in engineering and design, and its lower refresh rate hinders the smooth visuals that gaming and 3D applications demand. The Lenovo Legion Slim 7, with better resolution and brightness, provides a more vivid and sharp display suitable for both daily tasks and detail-oriented engineering work, although it doesn't have a high enough refresh rate to deliver the best experience for fast-paced gaming and 3D rendering. For users focused on general productivity or professional design work, the Legion Slim 7 is the preferred choice, while gamers and 3D artists may want to look for a laptop tailored to their specific needs with a high-refresh-rate screen.

Benjamin Herzig | November 2022
"The Lenovo Legion Slim 7 is a slim Legion notebook that is just as excellent with Nvidia & Intel. However, the Legion Slim 7i slightly sullied by lacklustre battery life. You get a slim aluminium chassis, great input devices, decent port selection, fast high-quality WQXGA display and great performance. Supporting Thunderbolt 4 is one advantage of the Intel/Nvidia model tested in this review. Moreover, this variant has slightly higher CPU performance as well as better GPU performance in certain applications (e.g. CUDA-based apps). The Lenovo Legion S7i is thin, premium and performant – but less efficient than its AMD counterpart."
