The Lenovo Legion Slim 5i is aimed more at gaming and demanding tasks with its higher performance hardware, so if you plan to play games or use intensive applications, it's better suited for those needs. However, because of these capabilities, it tends to be heavier and may have shorter battery life. The Lenovo ThinkBook 13s, on the other hand, offers more portability and longer battery life, making it suitable for general use such as browsing, office applications, and media consumption. If you prefer a balance between mobility and battery life over high performance, then the ThinkBook 13s would be the better choice. Give Feedback

The Lenovo Legion Slim 5i has a better screen than the Lenovo ThinkBook 13s for general use, gaming and AI, engineering and design, and content creation.
The Lenovo Legion Slim 5i comes with characteristics favorable for general activities and engineering, such as a high-resolution display and color accuracy that covers a broad range of the color spectrum, making it good for tasks that require detailed visuals and precise colors. However, its lower refresh rate limits its ability to display fast-paced gaming and 3D rendering smoothly, leading to a less optimal experience for those specific applications. Meanwhile, the Lenovo ThinkBook 13s also provides a good resolution and color accuracy for everyday and professional design work, but similarly falls short in the gaming and 3D arenas due to its less suited refresh rate.

"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 best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
