The ASUS ROG Strix G15 offers high performance, with a robust processor and graphics card, making it suitable for gaming, 3D rendering, and machine learning tasks. It has a larger storage capacity and more memory, which benefits intensive applications but also comes at a higher price and is heavier, affecting portability. The Dell Inspiron 15 3520 is more budget-friendly and lighter, making it easier to carry around, and it offers longer battery life. However, its lower-spec processor and integrated graphics are best for general use tasks and not suited for demanding software applications or gaming. Choose the ASUS if performance for demanding tasks is a priority and you're okay with investing more and having less portability; opt for the Dell if you need something for everyday tasks, with longer battery life and lower cost.

For general use, the ASUS ROG Strix G15's screen has better resolution and brightness, providing sharp images and good visibility under various lighting conditions, while the Dell Inspiron 15 3520 offers acceptable quality but may not be as vibrant or clear. In engineering and design, where accurate color reproduction is crucial, the ASUS likely has a wider color gamut, making it superior for tasks requiring precision in color work. However, for 3D applications and gaming that rely on smooth motion, the ASUS's screen falls short due to a lower refresh rate, making fast-paced visuals less fluid compared to screens designed with higher refresh rates for these purposes.

How the ASUS ROG Strix G15 and the Dell Inspiron 15 3520 compare to other laptops
"The ASUS ROG Strix G15 is a successful high-performance 15-inch laptop. The Asus ROG Strix impresses with an elaborate design and fast hardware. The latter can unleash its potential well in the large 15-inch case and achieve a decent performance boost compared to the previous generation. Especially the stunning 300 Hz display as well as the RTX 3070 and its generous TDP give gamers their money's worth. Asus didn't neglect seemingly small details, either, such as the keyboard and the maintenance options. The ROG Strix G15 offers a lot of pure performance and excellent workmanship in a 15-inch format, but connectivity leaves something to be desired."
"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."
