Bell 525 Relentless vs Daher Tbm 960 vs Gulfstream G700 vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Daher TBM 960 and Gulfstream G700 are fixed‑wing business aircraft, so they serve very different missions. The Bell 525 is a modern “super‑medium” twin‑engine helicopter aimed at offshore, corporate, and utility roles, with a long helicopter range of roughly 500–600 nautical miles and typically around a dozen-plus seats in an executive layout. The Robinson R66 is a light single‑engine turbine helicopter optimized for simplicity and cost, with a shorter range around 300 nautical miles and seating for about five including the pilot. The TBM 960 is a high‑performance single‑engine turboprop airplane for owner‑operators, optimized for efficient point‑to‑point travel, with range on the order of 1,500–1,700 nautical miles and typically 4–6 passengers plus a pilot depending on configuration. The Gulfstream G700 is an ultra‑long‑range large‑cabin business jet designed for intercontinental missions, offering roughly 7,500 nautical miles of range and commonly configured for about 13–19 passengers, with maximum seating higher depending on layout.
