If you prioritize a higher screen resolution and gaming or engineering performance, the Lenovo Legion Slim 7 with its dedicated graphics card and more powerful processor will suit you well, but it comes at a higher price and slightly more weight. On the other hand, the Acer Aspire 5 offers substantial cost savings and sufficient performance for general use and lightweight tasks, all while being lighter for better portability. It has a lower screen resolution and less processing power, which may affect usage in more demanding applications, so consider what you'll use the laptop for and if the price difference justifies the Lenovo's additional capabilities for your needs.

The Lenovo Legion Slim 7 16" is very good for general use, while the Acer Aspire 5 15 is good.
The Lenovo Legion Slim 7 16" offers a more powerful CPU and graphics unit, alongside a higher resolution and larger screen with better color coverage, which makes it very good for general use despite being slightly heavier and having a similar battery life to the Acer Aspire 5 15. While the Acer Aspire 5 15 is adequate for basic tasks with a competent CPU and a full HD screen, its lower screen quality and graphics make it just good for general use, though it benefits from being lighter and therefore more portable.

The Lenovo Legion Slim 7 16" is very good for engineering and design, while the Acer Aspire 5 15 is only fair.
The Lenovo Legion Slim 7 16" outperforms the Acer Aspire 5 15 in engineering and design due to its superior AMD Ryzen 7 processor and Nvidia RTX GPU, which are crucial for intensive tasks, and a higher quality screen with better resolution and color representation. While the Acer is slightly lighter and thus more portable, the Lenovo offers advantages in power and screen quality that cater to engineering software and detailed design work, despite being somewhat less portable and likely pricier.

The Lenovo Legion Slim 7 has a better screen than the Acer Aspire 5 15 for general use, gaming and AI, engineering and design, content creation, and software development.
The Acer Aspire 5's screen offers enough clarity and brightness for everyday tasks and work-related engineering software, but its limited color range and modest refresh rate aren't ideal for precise color work or fluid motion in gaming. On the other hand, the Lenovo Legion Slim 7's display, with superior brightness and color coverage, excels in providing crisp visuals for detailed design tasks and a pleasant viewing experience for general usage. However, despite the higher resolution and quality, the screen's lower refresh rate might not be the best for gaming, where fast-paced action requires quick screen updates for smoother play.

Sascha Mölck | November 2022
"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."

"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."
