The ASUS ROG Zephyrus G15 has a better screen than the Dell XPS 15 for general use, gaming and AI, and engineering and design, while the Dell XPS 15 has a better screen for content creation, and software development.
For general use, the ASUS ROG Zephyrus G15's screen likely offers a sharp, bright display with vibrant colors due to its resolution and panel technology, but the Dell XPS 15 also has a high-quality display that is similarly bright and clear albeit slightly less striking. In engineering and design, the ASUS might have a wider color range, appealing to professionals needing precision in color-critical tasks. However, for gaming and 3D purposes, the ASUS falls short due to a lower refresh rate, which makes fast-paced visuals less smooth compared to screens optimized for such tasks, whereas the Dell's performance is similarly limited for these uses.

How the ASUS ROG Zephyrus G15 and the Dell XPS 15 compare to other laptops
"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 2023 Dell XPS 15 is more or less exactly what you'd expect from the company flagship. Its fresh components deliver measurably superior power and longevity, while the machine's premium build and design remain intact. It may not be overly exciting, but XPS loyalists and upgraders should be more than happy."
