The Dell Inspiron 14 7435 is a bit more expensive and offers better performance with a faster processor, more storage, and double the RAM compared to the Dell Inspiron 15 3520. It has a smaller, higher resolution display that supports touch, which could be beneficial for creative tasks or note-taking. It's also a 2-in-1, providing tablet functionality. However, the Inspiron 14 has a slightly shorter battery life and is less suited for gaming due to its integrated graphics. In contrast, the Inspiron 15 is more budget-friendly and has a larger screen, which could be better for viewing media or working with multiple windows. It also has a higher refresh rate display, which can provide smoother visuals for fast-moving content. Its battery life is less than the Inspiron 14, it has less storage and RAM, and the processor isn't as powerful, which can affect multitasking and more demanding applications. This model will likely handle everyday tasks well, but for more intensive workloads or future-proofing, the Inspiron 14 might be the better choice. Give Feedback

Eric Grevstad | August 2023
"We see no shame in an economy laptop missing the four-star mark. Frankly, we considered giving the Inspiron 14 2-in-1 three-and-a-half stars for its low price, competitive performance, and long battery life. Unfortunately, working with a screen that can't deliver at least 300 nits of brightness is simply no fun to the point of detrimental. Still, if you're looking for a convertible laptop on a tight budget, it's worth keeping an eye on Dell's sales and discounts. That Lavender Blue model is fairly tempting."

"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."
