Gulfstream G500 vs Gulfstream G600 vs Dassault Falcon 6x

In category, the Gulfstream G500 and G600 are large-cabin, long-range business jets from the same family, while the Dassault Falcon 6X is a large-cabin, long-range jet positioned for ultra-wide-cabin comfort and efficient transoceanic missions. On range, the G500 is the shortest-legged of the three at about 5,300 nautical miles, suited to many transcontinental and some North Atlantic routes. The Falcon 6X extends that capability to roughly 5,500 nautical miles, generally comparable but slightly longer than the G500 depending on mission profile. The G600 leads on range at about 6,600 nautical miles, offering more city-pair flexibility, especially for longer nonstop international routes. For passenger capacity, all three typically seat around 12 to 16 passengers in common executive layouts, with maximum certified seating generally higher. In practice, the differences are less about headline seat counts and more about how operators prioritize mission length, cabin volume, and preferred cabin arrangements.
