If you prioritize high performance for engineering tasks or 3D work, the Lenovo Slim Pro 9i with a more powerful processor and dedicated graphics is the better option, at the expense of a higher price and a slightly shorter battery life. It also boasts a sharper screen with a higher resolution and brightness, suitable for content creation. However, if general use, affordability, and longer battery life are your main concerns, the Lenovo IdeaPad Slim 5i offers good performance with integrated graphics, making it less suitable for demanding graphics work but better for portability and extended use on a single charge.

The Lenovo Slim Pro 9i has a better screen than the Lenovo IdeaPad Slim 5i for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo IdeaPad Slim 5i may offer adequate resolution and brightness suitable for everyday tasks and productivity applications, ensuring comfortable viewing for general use, but its color gamut coverage might be limited which can affect precision required for engineering and design work, while the lower refresh rate would hinder the smoothness desired in gaming and 3D applications. The Lenovo Slim Pro 9i, on the other hand, likely boasts superior resolution, brightness, and wide color gamut which makes it excellent for detailed graphics work that engineering and design professionals need, but similarly to the IdeaPad, its refresh rate may not be high enough to satisfy the demands of high-end gaming or 3D rendering which often require fast and fluid visuals. Therefore, while both laptops have their strengths, users must weigh the importance of screen quality for their specific needs against other factors such as performance, price, and portability.
