The ASUS ROG Zephyrus G15 will suit you if you prioritize high performance in 3D applications, machine learning, and gaming, offering a superior GPU and refresh rate for fast-paced visuals. However, it's heavier and its battery life, while solid, can't match the ultra-portable ASUS Zenbook Flip S13, which excels in portability, battery life, and has a touchscreen with higher resolution, making it ideal for general use and crisp detail work. Consider the often slightly less expensive G15 for intensive tasks or the generally more expensive Flip S13 for on-the-go usage, touch capability, and better screen colors. Give Feedback

The ASUS ROG Zephyrus G15 is very good for engineering and design, while the ASUS Zenbook Flip S13 is good.
The ASUS ROG Zephyrus G15 is particularly adept for engineering and design due to its robust AMD Ryzen 9 processor paired with a powerful Nvidia RTX 3070 GPU, making it well-suited for compute-intensive tasks, while the ASUS Zenbook Flip S13, though also good for such tasks with its Intel i7 processor and Iris Xe graphics, doubles as a tablet with a higher-resolution screen which may benefit design work, but its less powerful graphics mean it may struggle with more demanding engineering simulations or 3D work.

Florian Glaser | February 2021
"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."

"The Asus Zenbook S 13 Flip is an ultra-sleek 2-in-1 convertible. A gorgeous OLED screen and lightweight magnesium chassis make this convertible a traveller’s dream. Its SSD isn’t fast, but it won’t hold you back in everyday use. Its battery life also isn’t class leading, but it’s hardly off the pace. Overall, the Zenbook S 13 Flip OLED holds its head high in the premium convertible category and is a smaller alternative to the Spectre x360 13.5 and the Yoga 9i Gen 7."
