LG Gram SuperSlim vs Samsung Galaxy Book4 Pro 360
The Verdict
Both ultraportable laptops excel in different areas, making this a nuanced choice. LG Gram SuperSlim impresses with its featherweight 2.18-pound design and OLED display, though its 1920x1080 resolution feels dated at this price point. Samsung Galaxy Book4 Pro 360 counters with a sharper 2880x1800 Dynamic AMOLED 2X display, 120Hz refresh rate, and superior battery life (15 vs 12 hours). Storage expansion via microSD card gives Samsung practical flexibility the LG lacks. Both share the Intel Core Ultra 7 155H and 16GB RAM, ensuring snappy performance. Samsung's 2Thunderbolt ports and USB-A connectivity offer better peripheral support. However, LG's 0.43-inch thickness edges Samsung's 12.8mm profile for portability obsessives. At $50 more, Samsung Galaxy Book4 Pro 360 delivers better value with its premium display, longer battery, and expandable storage—ideal for professionals prioritizing productivity and longevity.
