The model on right column is obviously a better choice just by looking at the specs sheet. It is equipped with the more expensive and powerful Snapdragon 820, so this LG G5 version will have better performance and faster LTE speeds. Otherwise, they have the same modular design, feature Quick Charge 3.0, 4K video capture, and work with all new attachable accessories like the Bang & Olufsen-powered LG Hi-Fi Plus or LG Cam Plus.
