Since you mentioned that the Acer Aspire 5 15 is significantly less expensive than the Lenovo Legion Slim 5, consider that the Acer might offer sufficient performance for everyday tasks like browsing the internet, working with office applications, and streaming video at a value price. However, the Lenovo Legion Slim 5, while more expensive, is likely designed with higher-end specifications that support gaming, 3D rendering, and more demanding engineering and machine learning software. It may also have a better display and build quality. So if you need a laptop primarily for general use and are budget-conscious, the Acer Aspire 5 is a good choice. On the other hand, if you need higher performance for specific, resource-intensive tasks and are willing to invest more, then the Lenovo Legion Slim 5 is the appropriate pick. Remember to weigh the need for portability and battery life, as gaming laptops often trade these features for more power and better graphics. Give Feedback

The Lenovo Legion Slim 5 is good for gaming and AI, while the Acer Aspire 5 15 is only fair.
The Acer Aspire 5 15 offers limited gaming capabilities primarily due to its integrated Intel Iris Xe graphics and a standard screen refresh rate of 60Hz, meaning it can handle some gaming but may struggle with more demanding titles and offer less smooth visuals. In comparison, the Lenovo Legion Slim 5 is equipped with a dedicated Nvidia RTX 4060 graphics card and a higher refresh rate screen at 144Hz, ensuring better performance and smoother gameplay which is more suitable for intensive gaming and 3D applications.

The Lenovo Legion Slim 5 is very good for engineering and design, while the Acer Aspire 5 15 is only fair.
The Lenovo Legion Slim 5 is rated higher for engineering and design use primarily due to its superior graphics card, the Nvidia RTX 4060, and a slightly better screen with higher resolution and refresh rate ideal for detailed work, when compared to the Acer Aspire 5 15 which uses an integrated Intel Iris Xe graphics and standard full HD display. While both have the same amount of RAM and similar CPUs, the Legion's gaming-grade GPU boosts its capacity for running complex simulations and rendering tasks that are common in engineering and design work.

The Lenovo Legion Slim 5 has a better screen than the Acer Aspire 5 15 for general use, gaming and AI, engineering and design, and software development.
If you prioritize a clear and vibrant display for everyday tasks like browsing the web and working with documents, the Lenovo Legion Slim 5 provides superior visuals with higher resolution and brightness than the Acer Aspire 5. However, for engineering and design work where precise color representation matters, both laptops have fair screen quality with adequate color gamut coverage, but neither is ideal because they don't excel in displaying the full range of colors professional designers need. For gaming and 3D applications, the Lenovo Legion Slim 5 falls short due to its lower refresh rate, making the Acer Aspire 5 also less suitable, but both will lack the fluid motion that a higher refresh rate screen offers.

"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."

Mark Knapp | August 2023
"The Lenovo Legion Slim 5 Gen 8 acknowledges that a gaming laptop doesn’t have to be as thick as possible and can still ensure adequate cooling when the muscles need flexing. To this end, in the Slim 5 Gen 8, it finds a neat balance of refined, trimmed-down design that still lets its internals cruise (even above their max power ratings). Lenovo then added in some high-end build quality with an altogether excellent keyboard that’s useful for both work and play."
