The Gigabyte Aero 17 has a better screen than the Lenovo Legion Slim 5i for general use, gaming and AI, engineering and design, and content creation.
The Gigabyte Aero 17's excellence for general use and engineering is due to its high-resolution display that delivers bright, sharp images and covers a broad range of colors, crucial for accuracy in design work. However, its lower refresh rate affects its performance in gaming and 3D tasks where smooth motion is key. The Lenovo Legion Slim 5i, while providing a very good general-use display with its decent resolution and brightness, falls a bit short for engineering due to less extensive color coverage, and also isn't ideal for gaming due to a lower refresh rate.

The Gigabyte Aero 17 and Lenovo Legion Slim 5i are both very good for engineering and design.
The Gigabyte Aero 17 stands out for engineering and design due to its high-resolution Mini LED screen which offers excellent brightness and color coverage, complemented by a powerful CPU, ample RAM, and a high-end GPU, making it suitable for demanding tasks like 3D rendering and detailed design work. While the Lenovo Legion Slim 5i features a newer generation CPU and a more portable design, its screen quality, though good, doesn't match the Aero 17, and the GPU, while capable, is a step down, making the Aero 17 the superior choice for intensive engineering and design use despite potentially higher operating noise and less portability.

How the Gigabyte Aero 17 and the Lenovo Legion Slim 5i compare to other laptops
"Not only is the Aero 17 a very good laptop for gamers but also for content creators. With the upgrade to the Intel Core i9-11980HK, Gigabyte particularly improved the system performance. In addition, the hardware package is rounded by the extremely fast SSD and 32 GB of working memory in dual-channel mode. Compared to the predecessor, the battery life is reduced only moderately, and the 4K display also basically keeps its good qualities."
"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."
