The Dell Inspiron 15 3520 is less expensive and provides a solid performance for general use with decent battery life and portability, but it's less suited for tasks like 3D rendering or engineering. The Lenovo IdeaPad 1 15" costs more but offers a touch screen, better performance for engineering and 3D/machine learning applications, and a more powerful CPU. If budget is a priority and you do not need advanced computing capabilities, the Dell may suit you. However, if you require a laptop for more intensive tasks and appreciate a touch screen, the Lenovo may justify the extra cost. Both have similar portability and screen size. 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."

Alex Iliev | April 2023
"The Lenovo IdeaPad 1 15" is affordable and pretty efficient. At the end of the day, the Lenovo IdeaPad 1 (15″, 2023) is one of the better affordable laptops money can buy right now. It has a decent performance, albeit coming from a CPU that is based on old architecture. Playing low-intensity games is possible but at low to medium settings. We are really happy with the cooling setup, but the main event here is the battery life. We got 9 hours of either Web browsing or video playback, which is a great result. Especially if you compare this device with the ASUS E410."
