The ASUS TUF Gaming F15 is a more affordable option and tends to be lighter, offering good gaming performance and a mid-tier graphics card. It's better for those who need a balance between cost and capability. The Lenovo Legion 9i is more expensive, but comes with a more powerful processor, superior graphics card, and more memory, making it better suited for very intensive tasks like 3D rendering or machine learning. The Legion 9i also boasts a higher resolution display, which can improve your experience when working on detailed visuals, but at the expense of battery life and portability. If you travel frequently or have a tighter budget, the ASUS may be the better choice, whereas if you require the highest performance for demanding applications and value screen quality, the Lenovo Legion 9i is likely more suitable.

The Lenovo Legion 9i has a better screen than the ASUS TUF Gaming F15 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, laptops with higher resolution and brightness provide clearer visuals and better viewing experiences, which is why the Lenovo Legion 9i stands out due to its superior display properties. In engineering and design, accurate color representation is important, and the Lenovo's coverage of color gamuts like DCI-P3 and Adobe RGB ensures that designs will be vibrant and true to life. However, for gaming and 3D applications where rapid on-screen action is common, a high refresh rate is crucial, and neither the ASUS TUF Gaming F15 nor the Lenovo Legion 9i offer optimal refresh rates for these tasks.

Allen Ngo | March 2022
"Aside from all the chassis updates, the new TUF Gaming is most notable for its much higher TGP target of 140 W compared to only 95 W on the previous generation. PC makers everywhere are using the same GeForce GPUs this year since Nvidia has yet to launch the successor to the mobile RTX 3000 series. The more demanding processors of the new TUF Gaming has directly impacted battery life and the size of the AC adapter. Don't expect runtimes to be longer than on the previous generation under most conditions and be prepared to carry around an even larger AC adapter than before."

"The Lenovo Legion 9i is meant as a top-end flagship showcase for enthusiasts, and on that, it delivers. You'll find flashier designs in this price tier—Razer’s all-metal build in a similarly sized laptop like the Blade 16, or monstrous 18-inch machines—but this is a well-thought-out laptop. The chassis is trim for a 16-inch powerhouse, the lid is unique, and bespoke liquid cooling takes performance to the next level."
