If your priority is gaming or professional tasks like 3D rendering and machine learning, the Gigabyte Aorus 15P is better suited due to its more powerful processor and graphics card but expect a higher price and less portability due to increased weight. On the other hand, if you're looking for a more budget-friendly option for general use such as browsing and office applications, and value a lighter laptop with longer battery life for routine tasks, the Dell Inspiron 15 3520 would be adequate.

The Gigabyte Aorus 15P is good for general use, while the Dell Inspiron 15 3520 is only fair.
The Dell Inspiron 15 3520, with a less powerful Intel i3 processor, less RAM, and lower screen color coverage, offers adequate performance for everyday tasks, but it falls short for demanding use, and its battery life is only fair. In contrast, the Gigabyte Aorus 15P benefits from a robust Intel i7 processor, a substantial amount of RAM, and superior screen quality, making it well-suited for intensive tasks, although it is heavier and has a shorter battery life compared to the Dell.

The Gigabyte Aorus 15P is very good for engineering and design, while the Dell Inspiron 15 3520 is only fair.
The Gigabyte Aorus 15P stands out for engineering and design use due to its much more powerful Intel i7 processor, substantial RAM, and high-end Nvidia RTX GPU, which collectively enable demanding tasks and complex simulations, along with a brighter and more color-accurate screen. In contrast, the Dell Inspiron 15 3520, with its basic Intel i3 processor, moderate RAM, and integrated graphics, offers only adequate power for less intensive applications, and its dimmer, less color-rich display may not be ideal for precision design work.

PCMag
Mark Knapp | January 2023
"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. Plus, those alternatives are much more enjoyable after work."

"The Aorus 15P is a high-end gaming laptop with fast 360 Hz display. Gaming performance in the Aorus 15P YD is very high thanks to the Nvidia GeForce RTX 3080 installed here. However, with the use of the Intel Core i7-11800H, CPU performance also closes in on the strong competition from AMD. SSD performance is excellent as well, and it leaves no room for criticism. Thanks to the built-in Intel Core i7-11800H, the system performance of the Aorus 15P YD increases significantly."
