The ASUS ROG Flow X16 has a better screen than the MSI Stealth GS66 for general use, engineering and design, software development, and content creation.
The ASUS ROG Flow X16 boasts a high-resolution display with excellent brightness and color accuracy, making it ideal for tasks that require visual precision, such as photo editing and design work, while its high-quality panel ensures sharp and clear images for everyday use. However, its lower refresh rate means it falls short for gaming and 3D applications, where smooth motion is crucial. On the other hand, the MSI Stealth GS66 offers a balance of good resolution and brightness, with decent color coverage that's suitable for both day-to-day tasks and professional design work, but, similar to the ASUS, its refresh rate isn't optimal for the fast-paced visuals required by gamers and 3D designers.

How the ASUS ROG Flow X16 and the MSI Stealth GS66 compare to other laptops
"Above all else, the Asus ROG Flow X16 is one thing - versatile! It is a thin, mobile work device, it's a 2-in-1, tablet, a powerful workstation and even a gaming PC. But something even more surprising: It does all of these things really well without making any big blunders. It's anything but a lazy compromise. Because, despite its compact dimensions and 2-in-1 functionality, the hardware isn't throttled and boasts, at least in turbo mode, above-average performance."
"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."
