Bell 525 Relentless vs Cessna 208b Grand Caravan Ex vs Gulfstream G700 vs Piper M600 Sls

The Bell 525 Relentless is a fly-by-wire, super‑medium helicopter aimed at executive and offshore missions. It typically carries around 12–16 passengers depending on layout, with a practical range on the order of roughly 500–600 nautical miles. The Cessna 208B Grand Caravan EX is a rugged single‑engine turboprop utility aircraft; it commonly seats 9 passengers (up to 14 in high‑density configurations) and offers roughly 900–1,000 nautical miles of range depending on payload and conditions. The Gulfstream G700 is a long‑range, large‑cabin business jet designed for intercontinental travel, usually configured for about 13–19 passengers, with a published range around 7,500 nautical miles. The Piper M600 SLS is a pressurized single‑engine turboprop positioned as an owner‑flown personal aircraft; it typically seats 5–6 passengers and has a range around 1,200–1,400 nautical miles. Overall, the G700 dominates range and cabin size, the Caravan emphasizes utility and short-field flexibility, the M600 balances speed and owner operation, and the Bell 525 trades runway independence for shorter point‑to‑point range.
