If you prioritize performance for tasks like 3D rendering, machine learning, or engineering software while also wanting a portable design, the ASUS ROG Flow Z13 with its latest Intel processor and Nvidia RTX graphics might be a good choice, although it has a shorter battery life and smaller screen size. On the other hand, if you prefer a larger display suitable for multitasking and creative work, with a high-resolution OLED touchscreen and more RAM for heavy loads, the ASUS ZenBook Pro Duo 15 may be preferable, but it's heavier and less portable. Both models are similarly priced with equal storage capacity, but the ZenBook has a higher battery capacity and might last longer on a charge. Give Feedback

The ASUS ROG Flow Z13 has a better screen than the ASUS Zenbook Pro Duo 15 for gaming and AI, while the ASUS Zenbook Pro Duo 15 has a better screen for general use, engineering and design, content creation, and software development.
The ASUS ROG Flow Z13 and ASUS ZenBook Pro Duo 15 both excel in screen quality for general use and engineering due to their high-resolution displays and superior brightness, creating sharp and vivid images, while their panel types provide wide viewing angles. Their color accuracy, covering a broad range of the color spectrum, makes them ideal for engineering and design tasks where precise color representation is necessary. However, both fall short for gaming and 3D because they lack the high refresh rates needed for smooth and responsive visuals that are crucial for these applications.

How the ASUS ROG Flow Z13 and the ASUS ZenBook Pro Duo 15 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."
"Benchmarks aside, the Asus ZenBook Pro Duo is hard to compare with other PCs. Its closest competition may be a multi-monitor desktop, or a laptop with an attached travel monitor. The Pro Duo is more portable and versatile than either of those options, especially with the software tools Asus has thrown on top. For a certain niche of artists, media creators, and gamers, all that might add up to something special, even if it’s unattainable for the rest of us."
