The Dassault Falcon 6X and Gulfstream G500 sit in the large-cabin, long-range class, while the Embraer Praetor 600 is a super-midsize jet and the Gulfstream G400 is typically positioned in the large-cabin, long-range segment below the G500. On range, the Falcon 6X is around 5,500 nautical miles, the Praetor 600 about 4,000 nm, the G400 about 4,200 nm, and the G500 roughly 5,300 nm, making the Falcon 6X and G500 the better fits for longer nonstop city pairs. For passenger capacity, typical comfortable layouts are generally about 12–16 for the Falcon 6X, about 8–12 for the Praetor 600, about 10–14 for the G400, and about 12–16 for the G500, with maximum configurations varying by operator. Overall, Praetor 600 emphasizes efficiency and value in the super-midsize category; G400 bridges into large-cabin range; Falcon 6X and G500 prioritize longer reach and larger-cabin comfort.
