The Lenovo Slim Pro 9i is very good for general use, while the Lenovo Legion 5 15" is good.
The Lenovo Slim Pro 9i has more RAM and a significantly better Mini LED display for screen quality, along with a slimmer design, making it more portable and having longer battery life, thus being rated higher for general use. On the other hand, while the Lenovo Legion 5 15" has a good display and enough RAM for most tasks, its heavier weight and shorter battery life compared to the Slim Pro 9i make it less ideal for portability and long usage away from a power source.

The Lenovo Slim Pro 9i and Lenovo Legion 5 15" are both very good for engineering and design, though the Lenovo Slim Pro 9i is somewhat better.
The Lenovo Slim Pro 9i excels in engineering and design due to its higher-quality Mini LED screen, more RAM, and a more robust CPU, which are crucial for intensive tasks; it also offers greater portability and a quieter operating noise. In contrast, the Lenovo Legion 5 15" provides a very good compromise with a solid GPU and screen resolution for engineering software, but it's heavier and doesn't offer as vivid screen colors or as much memory for multitasking.

The Lenovo Slim Pro 9i has a better screen than the Lenovo Legion 5 15" for general use, gaming and AI, engineering and design, content creation, and software development.
The Lenovo Legion 5 15" offers a balance suitable for general computing and engineering tasks due to its good resolution and brightness but falls short for gaming and 3D due to a lower refresh rate, which is crucial for smooth visuals in fast-paced environments. The Lenovo Slim Pro 9i excels in color reproduction and sharpness, appealing for engineers and designers who rely on precise color gamuts and high resolution for detailed work, yet like the Legion 5 15", it isn't ideal for gaming and 3D because of its less optimal refresh rate. Although both laptops have their strengths, neither is designed with the high refresh rate needed for the most demanding gaming or 3D rendering tasks.

Andreas Osthoff | September 2021
"The Lenovo Legion 5 15 is an affordable gaming laptop with a lot of power. The new AMD processor Ryzen 7 5800H offers plenty of performance and it is also very efficient. The combination with the fast 130W version of the GeForce RTX 3060 ensures high gaming performance. We also like the fast 165 Hz display with the 1080p resolution. The automatic graphics switching causes some problems with stutters, which are very annoying. If you do not need long battery runtimes, you should definitely deactivate the hybrid graphics mode in Lenovo's Vantage app. The Legion 5 15 is never silent."

"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."
