Dassault Falcon 6x vs Dassault Falcon 7x vs Dassault Falcon 8x vs Dassault Falcon 900lx vs Gulfstream G600

In category terms, the Falcon 900LX is a large-cabin trijet from an earlier generation, while the Falcon 7X and 8X are newer ultra-long-range trijets with more modern cabins and systems; the Falcon 6X is a newest-generation large-cabin twin focused on cabin comfort and transcontinental-to-long-range missions. The Gulfstream G600 is a super-midsize to large-cabin, long-range twin positioned against the 6X/7X class with higher cruise performance. For range, the Falcon 8X leads at roughly 6,450 nm, followed by the Falcon 7X around 5,950 nm. The Falcon 6X and Gulfstream G600 sit in a similar band at about 5,500–5,600 nm, while the Falcon 900LX is typically around 4,750 nm. Passenger capacity is broadly comparable: all are commonly configured for about 12–16 passengers. The 6X and G600 often seat up to around 14–16 in typical layouts, while the 7X, 8X, and 900LX can be arranged similarly, with the 8X generally offering the most flexibility and the longest-range comfort for larger groups.
