Bombardier Challenger 3500 vs Bombardier Challenger 650 vs Dassault Falcon 2000lxs vs Dassault Falcon 2000s vs Embraer Praetor 600 vs Gulfstream G280 vs Gulfstream G400

All seven are super‑midsize to large‑cabin business jets, with the Gulfstream G400 sitting at the top end as a new large‑cabin step‑up offering. In category terms, the Embraer Praetor 600, Challenger 3500, Falcon 2000S, and G280 are super‑midsize, while the Challenger 650 and Falcon 2000LXS are large‑cabin (with the 2000 series also often described as “large‑cabin, short/medium‑range”). Typical published range clusters as follows: Challenger 3500 and Praetor 600 are around 3,400–4,000 nm; Falcon 2000S is around 3,300–3,400 nm; Falcon 2000LXS is around 4,000 nm; Challenger 650 is about 4,000 nm; G280 is about 3,600 nm; and the G400 is longer‑legged at roughly 4,200 nm (final figures depend on certification and mission assumptions). Passenger capacity is broadly similar in typical layouts: most seat about 8–10 passengers, with maximum configurations commonly in the 12–19 range depending on model and cabin options (the G400 and Challenger 650 generally accommodate higher maxima than the super‑midsize group).
