LG Gram SuperSlim vs Samsung Galaxy Book4 360
The Verdict
Both laptops feature identical Intel Core Ultra 7 155H processors and 16GB RAM, but diverge significantly in design and display technology. LG Gram SuperSlim prioritizes extreme portability at just 2.18 lbs with a premium OLED 15.6" display offering superior contrast and color accuracy, though limited to 60Hz refresh rate. Samsung Galaxy Book4 360 weighs substantially more (3.63 lbs) but compensates with a 120Hz Dynamic AMOLED 2X touchscreen and 2-in-1 convertible design, delivering smoother scrolling and versatile usage modes. Battery endurance slightly favors Samsung (14 hours vs. 12 hours), while the LG offers marginally better port selection with dual Thunderbolt. At $350 less, Samsung provides exceptional value with convertible functionality and higher refresh rate, making it ideal for content creators and multitaskers. However, ultrabook enthusiasts prioritizing minimal weight and OLED picture quality should choose the LG Gram SuperSlim despite its premium pricing.
