The ASUS ROG Zephyrus G15 offers higher performance, especially for 3D, machine learning tasks, and gaming, thanks to its powerful AMD Ryzen processor and Nvidia RTX GPU. It comes with a higher resolution display that's also better for color-sensitive work, with a high refresh rate suited for gaming. However, it is less portable due to slightly heavier weight, and it's more expensive. On the other hand, the Gateway 15.6" could be more suitable for general use and lighter tasks given its Intel i5 processor and integrated graphics, which should offer adequate performance. It's lighter and less expensive, but it won't perform as well for intensive tasks and doesn't have as high display quality or battery life as the ASUS. Give Feedback

The ASUS ROG Zephyrus G15 and Gateway 15.6" are both good for general use, though the ASUS ROG Zephyrus G15 is somewhat better.
The ASUS ROG Zephyrus G15 outperforms the Gateway 15.6" with a more powerful CPU and a dedicated GPU, which enhances performance for a variety of tasks, sports a higher resolution screen with better color coverage, and offers a longer battery life, making it very good for general use despite being slightly less portable due to its lower weight. The Gateway 15.6", while also good for general use, is more affordable, sufficiently equipped with RAM and has a decent CPU, but it lags in terms of screen quality and doesn't have a dedicated graphics card, plus the battery capacity isn't specified, suggesting potentially shorter usage periods.

The ASUS ROG Zephyrus G15 is good for gaming and AI, while the Gateway 15.6" is only fair.
The ASUS ROG Zephyrus G15 boasts a high-end Nvidia RTX 3070 GPU and a 165Hz screen refresh rate, providing smooth and visually rich gaming and 3D experiences. In contrast, the Gateway 15.6" utilizes the integrated Intel Iris Xe graphics and has a lower 60Hz screen refresh rate, which results in less graphical performance and reduced motion fluidity, making it only fair for gaming and 3D uses.

The ASUS ROG Zephyrus G15 has a better screen than the Gateway 15.6" for general use, gaming and AI, engineering and design, software development, and content creation.
The ASUS ROG Zephyrus G15 offers high resolution and brightness, providing clear and vivid images essential for general use and detailed engineering tasks, while its color gamut coverage ensures accurate color reproduction crucial for design work. Despite these qualities, its lower refresh rate may not deliver the smooth visuals that gamers and 3D users seek. On the other hand, the Gateway's screen, while adequate for day-to-day tasks and non-critical design work with its fair resolution and brightness, does not reach the same level of color fidelity for professional design nor does it offer the high refresh rate sought after for gaming and 3D applications.

"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."
"Some concessions have to be made when shopping for a budget laptop. Walmart's Gateway Ultra Slim laptops succeeds on the affordability front and delivers serviceable specs and good battery life, though it's hard to claim it's the best (or even particularly good) at any particular aspect. Its build quality, especially the touchpad, is mediocre, and its performance is decent but doesn't lead the way. The Gateway does undercut the cost of some competitors and offers ample storage with good connectivity, so it's not to be ignored."
