The Dell Inspiron 15 3520 is a budget-friendly option with a decent display and good battery life for basic tasks, but its performance is more suited for general use than demanding applications. In contrast, the Samsung Galaxy Book3 360 costs more but offers a high-quality OLED touchscreen, longer battery life, and significantly better performance thanks to its advanced processor, making it ideal for more intensive tasks like engineering and 3D work. The Galaxy Book3 360 is also lighter and thinner, boosting portability, whereas the Inspiron's lower price may appeal more to those with straightforward computing needs and a tighter budget.

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."

Adam Speight | July 2023
"The Samsung Galaxy Book 3 360 isn’t a laptop that the Korean manufacturer has shouted from the rooftops about, and it seems to have gotten little attention from anywhere. But, it is absolutely a laptop worth paying attention to. Compared to higher-priced devices, like the Dell XPS 13 (2022) and Asus Zenbook S 13 OLED (2023), it manages to offer a similar day-to-day experience despite the price difference. It’s really hard to justify the extra cash unless a boosted display is a requirement of yours."
