The ASUS ROG Zephyrus G15 offers higher performance for intensive tasks like 3D modeling, machine learning, and gaming with its powerful processor and graphics card but at a higher price and heavier weight, resulting in less portability. Alternatively, the Dell Inspiron 15 3525 is more budget-friendly, lighter, and offers touchscreen convenience, but it's less suited for demanding tasks, providing modest performance which is adequate for general use. The ASUS has a significantly longer battery life compared to the Dell, which is important if you need to work on the go without frequent charging. If portability and cost are your primary concerns, the Dell Inspiron might be preferable, whereas for higher performance in resource-intensive applications, the ASUS ROG Zephyrus G15 is likely a better choice.

The ASUS ROG Zephyrus G15 and Dell Inspiron 15 3525 are both good for general use, though the ASUS ROG Zephyrus G15 is somewhat better.
The ASUS ROG Zephyrus G15 excels in general use with a powerful CPU and ample RAM, a high-resolution screen that enhances content clarity, and long battery life for extended usage, but is a bit heavier affecting its portability. Meanwhile, the Dell Inspiron 15 3525, with its fair performance for general use, offers a touch-enabled lower resolution screen and solid battery life in a lighter form factor, making it slightly more portable but less powerful in comparison.

The ASUS ROG Zephyrus G15 is very good for engineering and design, while the Dell Inspiron 15 3525 is only fair.
The ASUS ROG Zephyrus G15 comes with a high-end CPU, substantial RAM, and a powerful GPU which, paired with its high-quality screen, makes it excellent for demanding engineering and design tasks, but it is less portable and might be noisier under load. The Dell Inspiron 15, while more affordable and lighter for portability, has modest CPU, RAM, and GPU capabilities and a lower screen quality, which may limit performance in intense engineering and design applications, although it benefits from a quieter operation and possibly better keyboard and speaker quality for everyday use.

The ASUS ROG Zephyrus G15 has a better screen than the Dell Inspiron 15 3525 for general use, gaming and AI, engineering and design, software development, and content creation.
For general use, the ASUS ROG Zephyrus G15 offers a high-resolution display with excellent brightness and a panel type that delivers crisp images, while the Dell Inspiron 15's screen provides adequate clarity and brightness for everyday tasks but lacks the vibrancy of the ASUS. In engineering and design, the ASUS stands out with its wider color gamut coverage, ensuring accurate color representation critical for detailed work, whereas the Dell's more limited color range may not meet professional color standards. For gaming and 3D applications, the high refresh rate of the ASUS should ideally be a priority, but it falls short, making it less suitable for fast-paced visuals compared to other gaming-optimized screens, and the Dell, with a lower refresh rate, would further underperform in these scenarios.

"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."
"Dell's Inspiron 15 (3525) is a peppy-enough and affordable-enough home or remote work machine, but it's not very ambitious; it does little to go beyond the basics. More the concern: It’s readily overshadowed by a number of machines that outperform and outclass it. Even if the Inspiron can get the job done today, its competition has the mettle to keep doing the job tomorrow in a way the Inspiron simply can’t promise. Many of its slightly higher-end rivals have to be on sale (and frequently are) to match it on price, but the Inspiron 15 (3525) is outclassed even by some similarly priced options, making it a difficult recommendation."
