Bombardier Challenger 650 vs Cessna Citation Longitude vs Dassault Falcon 2000lxs vs Embraer Praetor 600 vs Gulfstream G280

Category-wise, the Bombardier Challenger 650 is a large-cabin business jet, the Cessna Citation Longitude and Embraer Praetor 600 are super-midsize jets, and the Gulfstream G280 and Dassault Falcon 2000LXS sit at the high end of super-midsize/“large light” and true large-cabin respectively, with the Falcon 2000LXS offering the most traditional large-jet cabin experience. On range, the Challenger 650 and Falcon 2000LXS are broadly similar at roughly 4,000 nautical miles. The Longitude is also near that mark (about 3,500–3,900 nm depending on profile), while the Praetor 600 is in the same general band (around 3,700–4,000 nm). The G280 typically leads this set for advertised range, at roughly 3,600–4,200 nm depending on source and assumptions. On passenger capacity, typical executive seating is about 8–12 across the group. The Longitude and Praetor 600 commonly seat 8–10. The G280 often seats 8–10 as well. The Challenger 650 and Falcon 2000LXS tend to accommodate 10–12 more comfortably, with higher maximum-certified layouts available.
