When selecting between the ASUS Zenbook Duo 14 and the MSI Stealth GS66, the ASUS offers a lower price with a unique dual-screen design, long battery life, and moderate weight, making it well-suited for general use and multitasking. It also includes a touchscreen, which can be beneficial for certain tasks. However, its performance for demanding work such as 3D rendering, machine learning, and gaming is limited compared to the MSI. On the other hand, the MSI is more expensive but boasts a high-performance processor and graphics card, higher RAM capacity, a fast refresh rate display ideal for gaming, and a keyboard with customizable RGB lighting. Although it has a more powerful battery, the MSI's battery life is shorter due to its higher performance components, and it is also heavier, which may affect portability. If you prioritize performance for gaming or professional creative work and are okay with a higher cost and lower battery life, the MSI Stealth GS66 is highly suitable. If you prefer a more affordable option with innovative features like dual screens and touchscreen capabilities for everyday use, the ASUS Zenbook Duo 14 would be a better fit. Give Feedback

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."
