The Dell Inspiron 15 3520 offers a balance of cost and capability, being more affordable and suitable for general use, but its heavier weight and lower battery life make it less portable. On the other hand, the LG Gram 16, while more expensive, delivers significantly better performance, longer battery life, and is extremely lightweight and portable, making it well-suited for on-the-go use and demanding tasks like engineering workflow and creative applications. Neither is designed for intensive gaming, but for tasks that require a high-quality display, the LG Gram 16 also has a higher resolution and more accurate color representation. Give Feedback

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 LG Gram 16 is a lightweight device with stability issues. The LG Gram 16Z90Q with a Core i7-1260P is made with portability in mind and places less of a focus on users with high demands on performance. The compact and light chassis is particularly practical when you are on the go. The device is not only comfortably small and lightweight, it also boasts a great battery life. When connected to mains, on the other hand, the 16-inch device is rather disappointing. The standard cooling mode causes extreme volatility in terms of CPU, SSD and iGPU performance. The meager stability of the chassis may also put off some potential buyers."
