Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Embraer Legacy 650e vs Embraer Praetor 600 vs Gulfstream G280 vs Gulfstream G400

In category, the Bombardier Challenger 3500 and Embraer Praetor 600 sit in the super‑midsize class, while the Gulfstream G280 is also super‑midsize but typically positioned at the top end of that segment. The Bombardier Challenger 650 and Embraer Legacy 650E are large‑cabin jets derived from earlier long‑cabin platforms, emphasizing cabin volume and comfort. The Gulfstream G400 is a newer large‑cabin aircraft positioned above the super‑midsize group. On range, the Challenger 3500 and Praetor 600 are broadly similar around the mid‑3,000‑nautical‑mile class, the G280 generally reaches farther in the upper‑3,000‑nautical‑mile class, and the Challenger 650 and Legacy 650E typically extend into the low‑4,000‑nautical‑mile class. The G400 is the longest‑legged here, in roughly the 4,000‑plus nautical‑mile category. For passenger capacity, these aircraft are commonly configured for about 8–10 passengers in the super‑midsize group, while the Challenger 650, Legacy 650E, and G400 more often seat about 10–13 depending on layout.
