The Lenovo Slim Pro 9i is very good for general use, while the ASUS TUF Gaming A15 is good.
The ASUS TUF Gaming A15, with its larger screen and more robust cooling, may appeal to those needing endurance and performance, but the Lenovo Slim Pro 9i excels in general use due to its superior RAM, higher resolution and brighter display, and lighter design, although it has a shorter battery life.

The Lenovo Slim Pro 9i has a better screen than the ASUS TUF Gaming A15 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, the Lenovo Slim Pro 9i offers top-tier screen clarity and brightness, making it excellent for a wide variety of tasks and viewing conditions, while the ASUS TUF Gaming A15 also delivers a sharp image but may not be as vivid or bright as the Lenovo. In the realm of engineering and design, the Lenovo's superior coverage of professional color gamuts enables more precise color work, essential for those fields, whereas the ASUS still provides good color representation, though not at the same level. However, for gaming and 3D applications, the ASUS falls short because of its lower refresh rate, which is less fluid for fast-paced visuals, whereas the Lenovo, despite its outstanding color and resolution, also doesn't cater to this need due to similar refresh rate limitations.

Andreas Osthoff | June 2023
"With the release of the TUF Gaming A15, Asos have concentrated on the essentials: gaming performance. Our base version, which can be had for around $1,169, already provided enough power to play current games smoothly in a native resolution of 1080p and with maximum details - thanks to its new Nvidia GeForce RTX 4050 Laptop. If you utilize upscaling, then you can even manage to run ray tracing."

"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."
