The ASUS ROG Flow X13, though more expensive, offers a higher-end processor and graphics card which translates into better performance for intensive tasks such as 3D modeling, machine learning, or gaming. It's also more portable, with a smaller screen and lower weight, but that comes at the cost of a smaller battery compared to the ASUS ROG Zephyrus G15. The Zephyrus G15 offers a larger screen and a longer battery life at a more affordable price, which could be better for users who prioritize screen real estate and less frequent charging over top-tier performance and portability.

How the ASUS ROG Flow X13 and the ASUS ROG Zephyrus G15 compare to other laptops
"The Asus ROG Flow X13 is not an off-the-shelf convertible. This quickly becomes clear when you take a closer look at the technical specs. The AMD Ryzen 9 5980HS is a state-of-the-art SoC with 8 cores and 16 threads, which also makes the 2-in-1 interesting as a work device. With 32 GB of RAM and a 1 TB SSD, gamers are also well taken care of. The dedicated Nvidia GeForce GTX 1650 Max-Q fits well into the overall concept and ensures a solid 3D performance. With the eGPU dock, which is equipped with a GeForce RTX 3080, the small convertible transforms into a full-fledged desktop replacement in terms of performance."
"As long as you're aware of the fact that the GeForce RTX 3080 laptop version can only unfold its potential to a limited extent due to Asus's low TDP setting and that it can be slower than a fast RTX 3070 laptop, the ROG Zephyrus G15 GA503Q cuts a fine figure. One of the biggest highlights turns out to be the WQHD panel, since it attracts customers with 165 Hz, relatively fast response times, FreeSync, and good color-space coverage. Other selling points are the surprisingly rich sound, the long battery life, and the sleek design. In terms of looks, the white edition stands out nicely from the competition."
