Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Dassault Falcon 6x vs Embraer Praetor 600 vs Gulfstream G500

In category, the Embraer Praetor 600, Bombardier Challenger 3500, and Bombardier Challenger 650 are typically positioned in the super-midsize to large-cabin crossover space, while the Dassault Falcon 6X and Gulfstream G500 sit firmly in the large-cabin, long-range class with higher overall capability and cabin volume. On range, the Praetor 600 and Challenger 3500 are broadly similar, generally suited to transcontinental missions in the roughly 4,000‑nautical‑mile class. The Challenger 650 extends that capability, commonly cited around the 4,000‑plus to ~4,600‑nautical‑mile range depending on assumptions. The Falcon 6X and Gulfstream G500 step up meaningfully, both generally advertised in the mid‑5,000‑nautical‑mile range, enabling more nonstop intercontinental city pairs. On passenger capacity, all can be configured for about 8–12 passengers in typical executive layouts. The Challenger 650 and 3500 commonly seat around 8–10, the Praetor 600 similarly around 8–10, while the Falcon 6X and G500 often support 10–14 in many configurations, with maximum certified seating typically higher than typical luxury layouts.
