The Lenovo Legion 9i has a better screen than the ASUS ROG Strix G15 Advantage Edition for general use, gaming and AI, engineering and design, content creation, and software development.
If you're focused on everyday tasks like browsing and watching videos, the Lenovo Legion 9i's superior resolution and brightness provide a sharper and more vibrant display. For engineering and design, where precise color representation is crucial, the Lenovo's wide color gamut ensures more accurate and rich visuals, which is essential for detailed work. However, when it comes to gaming and 3D applications where smooth motion is key, both laptops have screens that don't prioritize high refresh rates, leading to less fluid visuals compared to models designed specifically for those purposes.

"The Asus ROG Strix G15, as the first in a line of "AMD Advantage"-branded notebooks, is a statement that yes, you can get a premium AMD gaming notebook. Maybe you can't have it all, but you can get pretty close. The ROG Strix G15's combination of the AMD Ryzen 5900HX and Radeon RX 6800M, as well as other technologies that take advantage of them, make a potent, thin gaming machine. Powerful Dolby Atmos speakers and long battery life when you aren't gaming are nice bonuses."
"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."
