For better performance in engineering or intensive 3D tasks, consider the ASUS ROG Flow X13 with its advanced AMD processor and Nvidia GPU. However, the MSI Stealth GS66 offers a bigger screen and a higher refresh rate, which might be preferable for fast-paced gaming, although it may come at a higher price. The ASUS is lighter and more portable with a better battery life, making it suitable for on-the-go use. Both have similar RAM and backlit keyboards, but the MSI's RAM and storage are expandable. The ASUS has an advantage in color accuracy and touchscreen functionality, which may be beneficial for creative tasks. Give Feedback

The ASUS ROG Flow X13 has a better screen than the MSI Stealth GS66 for general use, engineering and design, software development, and content creation.
The ASUS ROG Flow X13 stands out for general use and engineering with its high-resolution display and bright screen, offering crisp and vibrant visuals, while its wide color gamut ensures accurate color reproduction for design work. In contrast, its lower refresh rate compared to gaming-oriented laptops makes it less suitable for gaming and 3D applications where smooth motion is crucial. The MSI Stealth GS66, while also providing a good resolution and brightness for everyday tasks and sufficient color accuracy for engineering and design, falls short in gaming performance due to a less optimal refresh rate which is key for fast-paced visuals.

How the ASUS ROG Flow X13 and the MSI Stealth GS66 compare to other laptops
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of 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."
