Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Dassault Falcon 2000lxs vs Dassault Falcon 2000s vs Embraer Legacy 650e vs Gulfstream G280

All six are super‑midsize business jets except the Dassault Falcon 2000S and 2000LXS, which are large‑cabin twins emphasizing cabin volume over peak range. The Bombardier Challenger 3500 is a super‑midsize with transcontinental capability (about 3,400 nm) and typically seats 8–10. The Bombardier Challenger 650 moves into the large‑cabin class with longer legs (about 4,000 nm) and higher typical capacity (10–12, sometimes more). Dassault’s Falcon 2000S is a large‑cabin aircraft optimized for shorter/medium missions (about 3,350 nm) with typical seating around 8–10, while the Falcon 2000LXS extends that concept with better range (about 4,000 nm) and similar typical seating. The Embraer Legacy 650E is a large‑cabin derivative known for a roomy, three‑zone feel, carrying roughly 10–13 and flying about 3,900 nm. The Gulfstream G280 is a super‑midsize performance leader with the longest range in this set (about 3,600–3,700 nm) and typically seats 8–10.
