Beechcraft Baron G58 vs Beechcraft King Air 360er vs Daher Tbm 960 vs Gulfstream G400

The Beechcraft Baron G58 is a piston twin in the light personal/business category, best suited to shorter regional trips; it typically carries about 4–5 passengers in addition to the pilot(s) and offers roughly 1,000–1,500 nautical miles of range depending on load and conditions. The Daher TBM 960 is a high-performance single‑engine turboprop positioned as a fast, efficient owner-flown business aircraft; it generally carries 4–6 passengers and commonly provides around 1,500–1,700 nautical miles of range. The Beechcraft King Air 360ER is a twin‑engine turboprop in the light-to-midsize utility/business category with more cabin volume and payload flexibility; it is often configured for about 6–9 passengers and is designed for extended missions around 1,800–2,200+ nautical miles (mission-dependent). The Gulfstream G400 is a large-cabin business jet aimed at long-range corporate travel; it typically accommodates about 8–12 passengers (with higher-density options) and is intended for roughly 4,000+ nautical miles of range, enabling true intercontinental-style missions compared with the turboprops and piston twin.
