The ASUS ROG Zephyrus G15 offers a higher refresh rate for an excellent gaming experience and overall great performance for engineering tasks due to its advanced GPU and CPU. However, it has a slightly heavier build which affects portability compared to the ASUS Zenbook Pro 15. The Zenbook Pro 15 features an OLED touchscreen, better for general use with longer battery life and lighter weight, but its performance for gaming or intensive engineering may not match the G15. If you prioritize doing intensive tasks like 3D rendering or gaming and don't mind the extra weight, the G15 is the better option, otherwise, for daily productivity and portability, the Zenbook Pro 15 is a suitable choice.

The ASUS ROG Zephyrus G15 is very good for engineering and design, while the ASUS Zenbook Pro 15 is good.
The ASUS ROG Zephyrus G15 is equipped with a more powerful CPU and GPU combo, which is essential for demanding engineering and design tasks, whereas the ASUS Zenbook Pro 15 provides a quality OLED touch screen that enhances visual work but has slightly less computing power. While both laptops have ample RAM, the Zephyrus G15's higher screen resolution and refresh rate may be more advantageous for detailed design work, and its higher-performing components favor engineering software, but the Zenbook Pro 15 offers a more portable form factor and a longer battery life, making it better for on-the-go use and multimedia consumption.

The ASUS ROG Zephyrus G15 has a better screen than the ASUS Zenbook Pro 15 for gaming and AI, and content creation.
The ASUS ROG Zephyrus G15 and Zenbook Pro 15 both have high resolution and brightness, offering crisp and vibrant displays suitable for everyday tasks and detailed engineering work, where color accuracy and a wide color gamut are essential. However, their lower refresh rates make them less ideal for gaming and 3D applications, which benefit from faster screen refreshes to provide smoother motion and less blur during fast-paced scenes. The panel types on both laptops, while providing excellent color and viewing angles, do not prioritize the high refresh rates sought by gamers and professionals in animation or 3D modelling.

The ASUS ROG Zephyrus G15 boasts a high-performance CPU and ample RAM, making it excellent for general tasks, while its superior screen quality enhances visual experience but is less portable due to its weight.

"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 Pro 15 offers a strong CPU, chassis, and display. One of the most popular 15.6-inch prosumer or multimedia laptops out there is the Dell XPS 15. Thus, comparisons between it and the Asus Zenbook Pro 15 are inevitable. Asus has a couple of tricks up its sleeve that XPS users are still missing out on including 1080p OLED and an AMD Ryzen CPU which help separate the Zenbook Pro 15 from the XPS 15. It also integrates a numpad and a few more port options albeit at the cost of a larger chassis size."
