The ASUS Vivobook S 15 OLED offers a vibrant OLED display with higher resolution and better color reproduction, making it ideal for those who value screen quality for entertainment or creative work. It also provides superior performance with its Intel Core Ultra 7 processor and dedicated Intel Arc graphics, suitable for more demanding tasks in engineering or light gaming. The laptop is slim and lightweight, enhancing its portability, and comes with a backlit keyboard and fingerprint reader for added convenience. However, it commands a higher price point.
In contrast, the Dell Inspiron 15 3520 is a budget-friendly option with a more modest feature set. It has an IPS display with standard Full HD resolution, which is adequate for general use but doesn't match the vividness of the ASUS's OLED screen. Its Intel i3 processor and integrated UHD graphics are sufficient for everyday tasks like web browsing, office applications, and streaming media, but it may struggle with more intensive applications. The Dell laptop is also bulkier and lacks advanced features like a backlit keyboard or biometric security.
Ultimately, if you prioritize display quality, performance, and portability, and are willing to invest more, the ASUS Vivobook S 15 OLED is the better choice. However, if your needs are limited to basic tasks and you're looking for a more affordable option, the Dell Inspiron 15 3520 will serve you well without the extra features. Give Feedback

"The Asus Vivobook S 15 OLED excels as a capable work machine at an affordable price. It offers commendable performance, thanks to its 12th Gen Intel chip, delivers quality on-screen entertainment with its 15.6-inch OLED display, and can (kind of) get you through a full day of work. Oh, and its special Asus Antibacterial Guard is a nice touch for those who like a clean laptop."
"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."
