Dassault Falcon 10x vs Dassault Falcon 8x vs Gulfstream G650er vs Gulfstream G700

Category-wise, the Dassault Falcon 10X and Gulfstream G700 sit at the top as ultra-long-range, large-cabin business jets, while the Gulfstream G650ER is also ultra-long-range but from the prior flagship generation, and the Dassault Falcon 8X is a long-range, large-cabin jet that is slightly smaller and typically less range-focused than the newest flagships. On range, the Falcon 10X and G700 are broadly comparable at about 7,500 nautical miles class, aimed at nonstop intercontinental city pairs. The G650ER is close behind at roughly 7,500 nautical miles as well, widely known for long nonstop missions. The Falcon 8X typically offers around 6,450 nautical miles, enabling many intercontinental routes but not matching the very longest legs targeted by the 10X/G700/G650ER. For passenger capacity, all can be configured for smaller executive loads, but typical layouts differ: the Falcon 8X often seats about 12–16, the G650ER about 14–18, and the larger-cabin Falcon 10X and G700 commonly seat around 12–19, with higher maximum-density configurations possible across the lineup.
