Which Should You Buy: Bombardier Challenger 650 or Gulfstream G450?

Bottom line: Choose the Challenger 650 for the widest cabin and value — a roomy, flat-floor large-cabin twin, durable and deeply supported. Choose the G450 for range and pedigree — more range, Gulfstream support and strong resale. On safety both are two-crew large-cabin twins with engine-out redundancy and excellent records; the divide is cabin width versus range, not safety. Widest cabin, or longer-range Gulfstream.
