When choosing between the ASUS ROG Zephyrus G15 and the HP Spectre x360 14, consider that the ASUS is typically geared towards high-performance activities like gaming and intensive tasks due to stronger graphics and processing capabilities, but this also means it's usually heavier and may have shorter battery life. The HP Spectre, on the other hand, offers more versatility with its convertible design and touchscreen; it's better suited for general use, on-the-go productivity, and longer battery life, making it more portable, but it won't handle demanding tasks as efficiently as the ASUS.

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 numbers don’t lie — the HP Spectre x360 14 (2024) is a star, and a hell of a one at that. From performance to battery life, this machine is a dream. But why didn’t I give it a perfect score? Well, I wish the display performed better and that there were more ports to go around. If you’re itching for someone a little cheaper that offers a brighter display and significantly more battery life, I can only recommend the MacBook Pro 14 as a suitable substitute. Otherwise, the HP Spectre x360 14 (2024) is the perfect choice for those who want a reliable premium laptop."
