The Acer Predator Helios 300 is slightly more expensive and offers good performance for general use and gaming. It has a robust build, decent battery life, and is capable of intensive gaming. However, it's heavier and has a lower resolution display compared to the Lenovo Legion Slim 5i. On the other hand, the Lenovo Legion Slim 5i, while generally cheaper, boasts better battery life, a higher screen resolution, and is lighter, enhancing its portability. It also has a larger default storage capacity. Both have the same amount of RAM and high-quality displays, but if performance in 3D rendering, machine learning, and engineering tasks is crucial, the Lenovo might be more suitable due to its newer processor and better GPU. If budget and portability are primary concerns, consider the Lenovo, but if you prefer somewhat better build quality and don't mind the extra weight, the Acer might be suitable for you. Give Feedback

The Lenovo Legion Slim 5i is very good for engineering and design, while the Acer Predator Helios 300 is good.
The Lenovo Legion Slim 5i outperforms the Acer Predator Helios 300 in engineering and design use primarily because it has a more advanced CPU and GPU, which are critical for intensive tasks, as well as a higher resolution and larger screen, enhancing the quality of visuals. Although both laptops share the same amount of RAM, the Legion Slim 5i's better overall performance comes at the cost of slightly lesser portability compared to the Helios 300, and it may have higher operating noise due to its more powerful hardware.

The Lenovo Legion Slim 5i has a better screen than the Acer Predator Helios 300 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, a laptop with a bright, high-resolution display with vivid colors, like the Lenovo Legion Slim 5i, offers a more visually pleasing experience for browsing and media consumption compared to a less vibrant screen on the Acer Predator Helios 300. Engineering and design tasks benefit from precise color reproduction, which is where displays with wide color gamuts excel, so the Lenovo's better coverage of color spaces such as DCI-P3 and Adobe RGB makes it suitable for these tasks. However, for gaming and 3D applications, a high refresh rate is crucial for smooth motion, and since both laptops have a poor rating in this aspect, they might not deliver the optimal experience for fast-paced or highly detailed 3D environments.

Christian Hintze | November 2022
"The Acer Predator Helios 300 review is an overclocked gaming laptop with a good display. The Predator is large, heavy, and loud, but also offers plenty of performance according to gamers. An overclocked gaming laptop - or its user - also has to struggle with the usual disadvantages we mentioned above. On the other hand, overclocking is optional, and those who like it quieter and can live with a few less frames per second can also switch to the significantly more moderate Standard mode. Then the Helios 300 won't be any louder than the competitors."

"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."
