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

All five are super‑midsize to large‑cabin business jets, with the Challenger 3500 and Gulfstream G280 sitting firmly in the super‑midsize category, and the Challenger 650 and Falcon 2000 variants offering a larger-cabin feel (the Falcons often described as large‑cabin/super‑midsize hybrids). For range, the longest‑leg options are typically the Challenger 650 and Falcon 2000LXS at about 4,000 nautical miles class, enabling more true transcontinental and some North Atlantic missions with favorable conditions. The Falcon 2000S follows slightly behind (roughly mid‑3,000s nm). The Challenger 3500 and G280 are also in the upper‑3,000 nm class, commonly suited to U.S. coast‑to‑coast and many transatlantic “edge” missions depending on winds, payload, and alternates. For passenger capacity, typical executive layouts across all are around 8–10 passengers. The Challenger 650 and Falcon 2000LXS generally accommodate higher maximum certified counts (often up to the mid‑teens), while the Challenger 3500, Falcon 2000S, and G280 usually top out lower (often low‑ to mid‑teens) but most commonly fly with 8–10 for comfort and baggage.
