If you prioritize higher storage capacity, more RAM, and better display features such as resolution and brightness, the Lenovo Slim Pro 9i is suitable for you, despite it being less affordable compared to the Lenovo Legion Slim 5. On the other hand, if gaming performance is crucial, and you prefer having features like a higher refresh rate and a larger screen, the Lenovo Legion Slim 5 is the better option. The Legion Slim 5 is heavier and less portable but offers a longer battery life, and its RTX 4060 GPU may handle certain types of intensive tasks better. The Slim Pro 9i, with its higher portability score and lighter weight, is aimed more at general and engineering use with its Intel i7 processor and RTX 4050 GPU, balancing performance and mobility.

"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 9i is an impressive laptop with a brilliant Mini-LED display, a powerful 100-watt version of Nvidia RTX 4050 graphics, and excellent connectivity. Having run the Cinebench benchmark again, we were impressed with the CPU performance. That makes the Slim Pro 9i is an easy recommendation, especially for those who care about GPU and CPU performance. It’s also a fantastic choice if you frequently view HDR movies and games on your laptop."
