When choosing between the ASUS Zenbook Duo 14 and the Lenovo ThinkBook 13s, consider the Lenovo if you prioritize higher RAM capacity, a higher resolution display, and it also tends to be less expensive. The ThinkBook is lighter in weight, making it more portable and suitable for on-the-go professionals. On the other hand, the Zenbook Duo offers a slightly larger screen and a dual-screen setup which may be beneficial for multitasking and productivity tasks. Its battery is also larger, which can translate to longer use between charges. Both have solid build quality and performance for general use, but the decision hinges on whether you value portability and screen resolution or innovative features and battery size. Give Feedback

The Lenovo ThinkBook 13s and ASUS Zenbook Duo 14 are both good for general use, though the Lenovo ThinkBook 13s is somewhat better.
The ASUS Zenbook Duo 14, while offering a larger screen and a very good portability score, is less suited for general use compared to the Lenovo ThinkBook 13s due to the ThinkBook's higher RAM, better screen resolution and quality, superior battery life, and higher portability due to being lighter and thinner. Additionally, the ThinkBook's more recent processor and operating system may provide a smoother user experience for everyday tasks.

The Lenovo ThinkBook 13s is good for engineering and design, while the ASUS Zenbook Duo 14 is only fair.
The ASUS Zenbook Duo 14 features a high-quality dual screen setup that's excellent for multitasking in engineering and design, yet its heavier build reduces portability compared to the Lenovo ThinkBook 13s, which offers solid engineering performance with a superior CPU and more RAM in a lighter package, but with a single higher-resolution display. Both laptops have competent GPUs for light design work but sharing the same integrated graphics, neither are suitable for intensive 3D tasks.

The Lenovo ThinkBook 13s has a better screen than the ASUS Zenbook Duo 14 for general use, gaming and AI, engineering and design, content creation, and software development.
For general use, both the ASUS Zenbook Duo 14 and Lenovo ThinkBook 13s offer screens with good resolution and brightness, providing clear and vivid images for everyday tasks like browsing and video streaming. When it comes to engineering and design, these laptops boast displays with a wide range of colors, ensuring that professionals can work with precision on projects requiring accurate color representation. However, for gaming and 3D applications, which demand quick image refresh for smooth visuals, neither of these laptops excels due to their lower refresh rates, which could lead to less fluid motion onscreen.

The Lenovo ThinkBook 13s and ASUS Zenbook Duo 14 are both only fair for gaming and AI.
The ASUS Zenbook Duo 14 and Lenovo ThinkBook 13s are fair for gaming and 3D because they both have integrated graphics, which are not as powerful as dedicated GPUs for graphics-intensive tasks, and their screens have a standard refresh rate, which is adequate for casual gaming but not optimal for high-end gaming that benefits from higher refresh rates. Both laptops have quality IPS displays which contribute to better screen quality, but their CPUs and integrated GPUs indicate they'll handle games and 3D applications decently, without reaching the higher performance levels of true gaming-specific laptops.

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 best thing about the ThinkBook 13S is that it’s a good deal. Business buyers looking for ThinkPad-level performance and software without ThinkPad pricing will probably find the ThinkBook a solid option. While nothing about it is really spectacular, it’s certainly unusual to see the ThinkBook’s screen resolution at a sub-$1,000 price, and its performance will be more than adequate for most office tasks. The generous port selection, 16:10 aspect ratio, physical webcam shutter, and clear audio are certainly icing on the cake."
