The Dell Inspiron 14 5420 is more expensive but offers a faster i7 processor, more RAM, and a dedicated Nvidia graphics card, which are better for engineering and intensive 3D tasks but also make the laptop less portable and have a moderate battery life. On the other hand, the Dell Inspiron 15 3520 is more affordable, has a larger screen, and a higher screen refresh rate, but it comes with a slower i3 processor, less storage, and integrated graphics, which makes it suitable for general use and casual tasks with a slightly lower battery life. Consider the 5420 for performance and the 3520 for budget and a bigger screen. Give Feedback

The Dell Inspiron 14 5420 is good for general use, while the Dell Inspiron 15 3520 is only fair.
The Dell Inspiron 14 5420 is better suited for general use due to its more powerful Intel i7 processor, higher RAM, and superior screen quality with better resolution and brightness, which enhances the overall experience; it also offers better portability with a longer battery life, making it more convenient for on-the-go use. In contrast, the Dell Inspiron 15 3520, while still capable for general tasks, has a less powerful Intel i3 processor, less RAM, and a lower screen quality, which may not be as sharp or bright, and its portability is somewhat compromised with shorter battery life despite a larger screen.

The Dell Inspiron 14 5420 is good for engineering and design, while the Dell Inspiron 15 3520 is only fair.
The Dell Inspiron 14 5420 offers better performance for engineering and design thanks to its more powerful Intel i7 processor, double the RAM, and a dedicated Nvidia graphics card, which are key for software in those fields, while also providing a higher quality screen with better resolution and color accuracy. Conversely, the Dell Inspiron 15 3520, with a more basic Intel i3 processor, integrated graphics, and less RAM, manages everyday tasks well but may struggle with the demands of engineering software, and its larger size, while offering a numeric keypad, makes it less portable.

The Dell Inspiron 14 5420 has a better screen than the Dell Inspiron 15 3520 for software development, and content creation, while the Dell Inspiron 15 3520 has a better screen for gaming and AI.
For general use, both the Dell Inspiron 14 5420 and 15 3520 will meet most needs as their screen resolution and brightness are sufficient for everyday tasks like web browsing, office work, and video streaming. However, for engineering and design professionals requiring accurate color representation, these models fall short due to less coverage of professional color gamuts, which is critical for precise visual work. When it comes to 3D and gaming, the screen's slower refresh rate on these Dell models may not provide the smooth visual experience desired by enthusiasts and professionals in fast-paced environments or those requiring high frame rates.

How the Dell Inspiron 14 5420 and the Dell Inspiron 15 3520 compare to other laptops
"If laptops were food, then the Dell Inspiron 14 5420 is arguably a Big Mac. There are cheaper and more expensive options, but this arguably represents the baseline of quality and value in the world of mobile computing… something that’s underlined by the attractive $1,279 price tag."
"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."
