If you prioritize a larger screen with higher resolution and can accommodate less portability and a heavier build, the Lenovo Legion 7 would be a solid choice; it's also typically less expensive and offers more built-in storage. However, if you prefer lighter weight, longer battery life, a more premium build, and potentially snappier performance due to a more powerful GPU variant, the MSI Stealth GS66, while at a higher price point and with less storage, might better suit your needs. The MSI model also features a higher refresh rate display, beneficial for fast-paced gaming, but at a lower resolution. Both laptops are capable of heavy tasks like 3D rendering and intensive gaming, but remember, the MSI Stealth GS66 will likely be more portable for on-the-go use. Give Feedback

The Lenovo Legion 7 has a better screen than the MSI Stealth GS66 for general use, and engineering and design, while the MSI Stealth GS66 has a better screen for gaming and AI.
When choosing between the Lenovo Legion 7 and the MSI Stealth GS66 for general usage, the Legion 7 offers a superior screen due to its higher resolution and brightness, providing crisper images and better viewability in various lighting conditions. For engineering and design tasks, the Legion 7 again leads with a wider color gamut, supporting more accurate color reproduction, which is essential for such precision work. However, for gaming and 3D applications, both laptops fall short due to a lower refresh rate, meaning they aren't as smooth in displaying fast-moving images, which could detract from the immersive experience desired in these areas.

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 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."
