The Lenovo Slim Pro 9i is very good for general use, while the Lenovo Legion 7 is good.
The Lenovo Slim Pro 9i is rated higher for general use than the Lenovo Legion 7 primarily because it boasts double the RAM, a superior screen technology and quality, and has a better thermal management despite being lighter and thinner, which enhances its portability. However, the Legion 7 offers more robust CPU and GPU performance for intensive tasks, and if those are a priority over screen quality and portability, it might be a more suitable choice.

Andreas Osthoff | September 2022
"The Lenovo Legion 7 is a fast 16-inch gamer with 165 Hz display. The new Lenovo Legion 7 is a very good gaming notebook that, despite its comparatively compact compact 16-inch case, does not have to do without the most powerful components. Thanks to good cooling, no compromises are made in terms of performance. Both the Core i9-12900HX and the GeForce RTX 3080 Ti perform at a very high level."

"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."
