The ASUS Vivobook S 15 OLED is slightly less expensive than the Dell Inspiron 14 5420 and offers a larger OLED screen with higher resolution and better color coverage, making it more suitable for tasks that benefit from high-quality visuals. It also has a high-performance processor suited for intensive tasks but has shorter battery life. The Dell, while slightly more expensive, has a dedicated graphics card, a professional appearance, longer battery life, and a more portable design, though it has less storage space and the IPS screen can't match the ASUS OLED for color and contrast. Consider the ASUS if your priority is performance and display quality for tasks like photo editing, and the Dell if you need something more portable with ample battery life for general productivity.

Darragh Murphy | November 2022
"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."
