ASUS ZenBook 14 OLED (UX3405, 2024) vs Samsung Galaxy Book4 Pro 360
The Verdict
Both laptops share Intel Core Ultra 7 155H processors and 16GB RAM, but differ significantly in value and form factor. ASUS delivers a 14-inch OLED display with 600-nit peak brightness, superior color accuracy, and a slim 14.9mm chassis weighing just 1.2kg, making it exceptionally portable. The 1TB SSD is double Samsung's base storage, and 18-hour battery life beats the Galaxy Book4 Pro by 3 hours. Samsung counters with a larger 16-inch Dynamic AMOLED 2X screen (excellent but dimmer at 400 nits), 2 USB-C ports versus zero on the ASUS, microSD expansion, and a rotatable 360-degree hinge for tablet mode. The Samsung weighs 1.66kg and measures thicker at 12.8mm. At $1299, the ZenBook offers substantially better value: you gain portability, longer battery, double the storage, and a brighter OLED panel for $450 less. The Galaxy Book4 Pro 360 justifies its premium mainly through the larger screen and convertible design, which matter only if you need a tablet experience. For most users prioritizing productivity and travel efficiency, the ASUS ZenBook 14 OLED provides superior everyday performance at a significantly lower price point.
