The Lenovo ThinkBook 13x has a better screen than the Lenovo Legion Slim 5 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo Legion Slim 5's screen offers suitable clarity and brightness, making it easy on the eyes during daily tasks, but the ThinkBook 13x outshines it with a more vibrant and sharper display. Both laptops have displays with color gamuts that should satisfy users working in engineering and design, ensuring accurate color reproduction for detailed projects. However, both fall short for gaming and 3D purposes due to their lower refresh rates, which can't deliver the smooth visuals desired in high-paced gaming scenarios where motion is more critical.

Although they have very similar scores, PerfectRec considers Lenovo Legion Slim 5 to be very good for engineering and design, while the Lenovo ThinkBook 13x is good.
The Lenovo Legion Slim 5 stands out for its powerful CPU and GPU, making it ideal for demanding engineering software and enhancing screen quality for design work, while also offering substantial RAM for multitasking; however, its portability is somewhat less than lighter laptops like the Lenovo ThinkBook 13x, which offers a balance with decent performance for engineering tasks and benefits from superior portability, a quality keyboard, and quieter operation. The ThinkBook 13x, while not as powerful, still delivers adequate performance for many engineering applications and boasts a high-quality screen, but the speakers may not match the Legion's audio capabilities.

PCMag
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."
