The ASUS ROG Zephyrus G15 offers slightly better overall performance for intensive tasks like 3D modeling, machine learning, or gaming due to its powerful processor and GPU. It also has a better screen in terms of resolution, colors, and refresh rate which can enhance the experience for gaming and creative work, but it comes at a higher price and with less portable design. Conversely, the HP Omen 15 is more affordable and provides longer battery life, making it more suitable for users who prioritize portability and cost over peak performance. While its performance is still solid for most use cases, there is a compromise in screen quality and build compared to the ASUS. Give Feedback

The ASUS ROG Zephyrus G15 has a better screen than the HP Omen 15 for general use, gaming and AI, engineering and design, and content creation.
If you prioritize a vivid and sharp display for everyday tasks and professional design work, the ASUS ROG Zephyrus G15 stands out with its higher resolution and brighter screen, offering a wider color gamut that's crucial for color accuracy in engineering and design. However, if your main focus is on gaming and 3D applications, both laptops may not meet your expectations due to lower refresh rates, with the ASUS potentially offering a slightly better visual experience due to its superior panel quality. In deciding between the two, consider how much time you'll spend on gaming compared to other tasks, as screen quality for general and professional use is more of a strength for the ASUS, while neither is optimized for high-performance gaming.

"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."

"We consider around 1,260 Euros (~$1530) for a Ryzen 7 4800H, a GeForce RTX 2060, a 512 GB SSD and 16 GB dual-channel RAM to be a good offer that appeals to price-conscious gamers. Very high details are rarely a problem in the native resolution of 1,920 x 1,080. Buyers will also be spoiled with a top-notch battery life that even beats most other notebook classes. If HP now improves the speed of the WLAN module, the stability of the case and the repeatedly criticized picture quality, the competition will have to dress extra warmly."
