The Dell Inspiron 16 5620 offers more storage and memory, a faster processor, and a longer battery life than the Dell Inspiron 15 3520, making it better suited for intensive tasks like engineering work. It also features a slightly larger and higher resolution screen, which provides a little more vertical space and makes multitasking easier. However, it's heavier and slightly less portable than the 15-inch model. If portability and cost are your main concerns and your tasks are relatively light, such as web browsing and document editing, the 15 3520 may be a better and more cost-effective option.

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."

"If the world is exciting enough right now, you can do far worse than a solid performer that you know will get the job done. Our review model is as powerful as you'd want an office machine to be unless you're performing specialist tasks and the price point is pretty attractive (unless work will let you have a MacBook Air instead)."
