Dassault Falcon 6x vs Embraer Praetor 600 vs Gulfstream G400

The Dassault Falcon 6X, Embraer Praetor 600, and Gulfstream G400 sit in different parts of the long-range business jet spectrum. The Praetor 600 is best described as a super-midsize jet, optimized for efficient transcontinental missions; it typically carries about 8–12 passengers and offers roughly 4,000 nautical miles of range. The Falcon 6X and Gulfstream G400 are larger-cabin, long-range jets, aimed at higher comfort and nonstop intercontinental capability. The Falcon 6X is generally positioned in the large-cabin, ultra-long-range class, commonly seating around 12–16 passengers with approximately 5,500 nautical miles of range. The Gulfstream G400 is also a large-cabin, long-range aircraft, typically arranged for about 12–16 passengers, with published range around 4,200 nautical miles. In practical terms, the Praetor 600 competes on value and operating efficiency for fewer passengers and shorter long-haul missions, while the Falcon 6X emphasizes maximum range and cabin volume, and the G400 targets a balance of Gulfstream cabin comfort with long-range capability.
