Bombardier Challenger 650 vs Bombardier Global 5500 vs Dassault Falcon 6x vs Embraer Legacy 650e vs Gulfstream G400

By category, the Bombardier Challenger 650 and Embraer Legacy 650E sit in the large-cabin business jet class, while the Bombardier Global 5500, Dassault Falcon 6X, and Gulfstream G400 are in the long-range, ultra‑long‑range/large‑cabin segment. On range, the Challenger 650 and Legacy 650E are typically used for transcontinental missions, with roughly mid‑4,000 nm class capability. The Falcon 6X, Global 5500, and G400 step up into true long-range flying, generally around the 5,500–6,500 nm class depending on configuration and conditions; in this group, the Falcon 6X and Global 5500 are commonly viewed as having the longest published reach, with the G400 close behind. For passenger capacity, all can be configured for about 8–16 passengers, but their comfort at higher counts differs. The Challenger 650 and Legacy 650E often shine with 8–12 in a roomy layout. The Global 5500, Falcon 6X, and G400 typically support 10–16 more comfortably thanks to larger cabins and longer-range mission profiles.
