The ASUS ROG Zephyrus M16 offers a better GPU and higher resolution display with a taller aspect ratio, which is excellent for multitasking and creative tasks where screen real estate is important. However, the MSI Stealth GS66 features a faster screen refresh rate useful for gaming and may be preferable if you prioritize a smoother visual experience. The MSI also has slightly better battery life, which could be advantageous if you often work on the go. Both laptops are similar in weight and offer high-quality keyboards and build, but the ASUS may come at a somewhat lower cost. If you're looking for high performance in 3D rendering or machine learning, the ASUS has the edge, while for ultra-fast gaming displays, the MSI might be more appealing. Give Feedback

Christian Hintze | March 2023
"The ASUS ROG Zephyrus M16 is not yet as optimised as its predecessor. Compared to the previous gen, performance and efficiency have improved significantly. What's more, the wonderful, Mini-LED Nebula display is a contender for the main highlight and almost manages to put the CPU and GPU in the shade. We already found its predecessor to be a well-rounded and well-optimised gaming machine. Generally, but not unequivocally, that also applies to the new Asus M16. Similar to most of the current, new laptops, we are dealing with a double generational leap in terms of the CPU and GPU. However, this change doesn't always run smoothly."

"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."
