If you prioritize high performance for tasks like 3D rendering, machine learning, or other intensive engineering applications and gaming, and you don't mind a heavier laptop with a more gamer-centric design, the ASUS ROG Strix G15 Advantage Edition would be a solid choice, especially as it generally comes at a slightly lower price. On the other hand, the MSI Stealth GS66, while typically more expensive, offers a more premium build, more portability due to its lighter weight, a higher screen refresh rate which can be beneficial for fast-paced games, and a longer battery life, making it suitable for both work and play if you're frequently on-the-go.

How the ASUS ROG Strix G15 Advantage Edition and the MSI Stealth GS66 compare to other laptops
"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 MSI Stealth GS66 is powerful enough for QHD. The Core i7-12700H and the GeForce RTX 3070 Ti found in the 12UGS model that we tested run all modern games smoothly in the native QHD resolution. The 15-inch display is very fast with its 240 Hz refresh rate, and it also offers a great color space (almost 100% DCI-P3) on top of that, which should please gamers as well as content creators, although we would have still wished for a higher brightness. Case, input devices, and connectivity (Thunderbolt 4) are at a good level. However, among other things, the GS66 loses points due to the high temperature development in 3D mode and its poor webcam."
