For tasks requiring high performance in 3D rendering, machine learning, or engineering applications, the ASUS ROG Flow Z13 with its newer and more robust GPU and CPU could be a better fit. However, the MSI Stealth GS66, with its larger screen and higher screen refresh rate, might be preferred for intensive gaming, though its performance in demanding tasks is slightly lower compared to the ASUS. The ASUS offers a more portable design due to its smaller size and lighter weight, which can be important if mobility is a priority. Both have solid build quality, though the ASUS may have slightly better heat management. If price is a concern, the ASUS is often less expensive, though it comes with half the storage capacity of the MSI. The ASUS's touchscreen feature and compatibility with 2-in-1 use add versatility. Battery life is slightly better on the ASUS, but neither is particularly long-lasting, so frequent access to power may be necessary. Give Feedback

The ASUS ROG Flow Z13 has a better screen than the MSI Stealth GS66 for general use, engineering and design, software development, and content creation.
The ASUS ROG Flow Z13 offers a high-resolution display and vibrant colors, which is ideal for tasks like web browsing and document editing, as well as precision work in engineering and design that rely on accurate colors. On the other hand, the MSI Stealth GS66 provides adequate clarity and color representation for everyday use and professional work, though it also doesn't excel in gaming because of its limited refresh rate. Neither model supports the high refresh rates that gaming and 3D applications benefit from, which can result in less fluid motion and responsiveness during gameplay or 3D rendering.

How the ASUS ROG Flow Z13 and the MSI Stealth GS66 compare to other laptops
"The Asus ROG Flow Z13 is a gaming tablet with powerful Alder Lake i9 CPU. The ROG Flow Z13 impresses with its good cooling. After our review, the impression is predominantly positive. Besides a very fast Alder Lake CPU and stable gaming performance, especially the cooling system is surprisingly effective and quiet. You can use the integrated speakers without any issues while gaming. The 1200p display in the 16:10 format also impresses with good color reproduction and high brightness. Since the battery runtimes aren't particularly long as it is, we wouldn't recommend the optional 4K panel."
"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."
