Beechcraft King Air 360 Er vs Enstrom 480b vs Gulfstream G700 vs Piper M600 Sls

The Beechcraft King Air 360ER is a twin‑turboprop utility aircraft suited to regional and remote operations, offering long endurance for its class (roughly 1,500–1,800 nm) and typically seating about 6–9 passengers depending on configuration. The Enstrom 480B is a single‑engine turbine helicopter, optimized for short‑range missions and vertical access; its range is far shorter (about 300–400 nm) and it generally carries around 4–5 passengers plus a pilot. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet designed for intercontinental travel, with range on the order of 7,000+ nm and a typical passenger load around 13–19 (with higher-density layouts possible). The Piper M600 SLS is a single‑engine turboprop personal/business aircraft, positioned between owner‑flown utility and light business travel, with range roughly 1,000–1,400 nm and seating commonly 5–6 passengers. Overall, the G700 leads by a wide margin in range and cabin capacity, the King Air 360ER emphasizes versatile regional capability, the M600 SLS targets efficient owner operations, and the 480B trades speed and range for helicopter access.
