The ASUS Zenbook Duo is more wallet-friendly and better for multitasking with its dual-screen setup, offering solid performance for general use. Its portability is very good due to its lighter weight and longer battery life, making it suitable for on-the-go work. However, the MSI Stealth GS66, with its high-end price, features a more powerful main processor and GPU, making it well-suited for demanding tasks like 3D modeling, machine learning, or intensive gaming. It sports a higher refresh rate display which is excellent for fast-paced gaming or video editing. The Stealth GS66 also provides a better overall build quality and a superior keyboard, but it is heavier and has a shorter battery life, which impacts its portability. If budget is a concern and you need a reliable, portable laptop for everyday tasks, go with the ASUS; if performance in resource-intensive applications is a priority and you can handle a higher cost, opt for the MSI.

Allen Ngo | May 2020
"The Asus ZenBook Duo's second screen is like the Apple Touch Bar, but better. Most would agree that having two screens instead of one can really boost productivity and the ZenBook Duo is no different in this regard. It's tough going back to just one screen after becoming accustomed to spacious dual-screen setups. For a laptop form factor, however, users will have to accept some compromises. Firstly, weight is the most obvious drawback as the system is several hundred grams heavier than a regular ZenBook 14. Additionally, colors on the second screen will not be as vivid as the main display."

"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."
