The ASUS ROG Flow Z13, being higher-priced, typically offers stronger performance suited for gaming and intensive tasks due to better graphics and cooling systems; however, it's bulkier, which affects portability. In contrast, the Lenovo ThinkBook 13x boasts a slim design for easy carrying and usually has a longer battery life, making it ideal for on-the-go business use and general productivity, but it may not handle heavy-duty applications as effectively as the ASUS. Your choice should reflect whether performance or portability and battery life are more important for your specific needs. Give Feedback

Although they have very similar scores, PerfectRec considers ASUS ROG Flow Z13 to be very good for general use, while the Lenovo ThinkBook 13x is good.
The ASUS ROG Flow Z13 offers high CPU performance and ample RAM, which along with its superior screen quality, make it very good for demanding tasks, but its gaming-oriented design might reduce its portability and battery life compared to more traditional laptops. The Lenovo ThinkBook 13x, with its balance of CPU, RAM, and a focus on portability and battery life, is well-suited for general use, providing a comfortable keyboard and quieter operation, without the emphasis on gaming capabilities.

Although they have very similar scores, PerfectRec considers ASUS ROG Flow Z13 to be very good for engineering and design, while the Lenovo ThinkBook 13x is good.
The ASUS ROG Flow Z13, with its high-performance CPU, ample RAM, and dedicated GPU, offers superior power and screen quality for demanding engineering applications, but it's heavier and could be noisier due to its cooling system.

Andreas Osthoff | March 2022
"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."
