For general use, both laptops have similar performance, but if you require longer battery life and a more portable laptop, the Lenovo Slim Pro 7 14 is superior. It's also touchscreen enabled, which the Legion Slim 5i lacks. However, if you're interested in intensive gaming, 3D rendering, machine learning, or other demanding engineering tasks, the Legion Slim 5i has a more powerful graphics card, which translates to better performance in those areas. The Slim 5i's battery life is shorter, and it's heavier, so keep that in mind if you plan to carry your laptop around often. The Slim Pro 7 14's lighter weight and longer battery life come at the cost of lesser performance in graphics-intensive tasks. Give Feedback

The Lenovo Legion Slim 5i is very good for engineering and design, while the Lenovo Slim Pro 7 14 is good.
The Lenovo Legion Slim 5i stands out for engineering and design use largely due to its high-performing CPU, ample RAM, and a more powerful GPU, which contribute to faster processing and better handling of graphics-intensive tasks, alongside a high-quality screen. Although the Lenovo Slim Pro 7 14 is also well-suited for these tasks with comparable RAM and a good quality screen, it is equipped with a slightly less powerful CPU and GPU, making it better for those prioritizing portability and a quieter operating noise.

Although they have very similar scores, PerfectRec considers Lenovo Slim Pro 7 14 to be very good for general use, while the Lenovo Legion Slim 5i is good.
The Lenovo Slim Pro 7 14 offers a superior balance of high-quality screen, capable CPU, and ample RAM which enhance everyday tasks, along with greater portability and longer battery life, making it very good for general use. In contrast, while the Lenovo Legion Slim 5i also has a solid CPU and sufficient RAM, its larger size, shorter battery life, and slightly lower screen quality compared to the Slim Pro 7, render it simply good rather than very good for such purposes.

"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."

"The Lenovo Slim Pro 7 is an attractive, portable laptop that’s ideal if you need a combination of CPU and GPU performance. It also nails the fundamentals with solid connectivity, an enjoyable keyboard, a large touchpad, and top-notch webcam. Display quality is a weakness, but it’s an acceptable compromise for the laptop’s extremely competitive $1,199 MSRP. The Slim Pro 7 is a versatile, affordable laptop and hard to beat for the price."
