Airbus Helicopters H160 vs Bell 525 Relentless vs Embraer Legacy 500 vs Gulfstream G280 vs Leonardo Aw139 vs Sikorsky S 76d

By category, the Airbus Helicopters H160, Leonardo AW139, Sikorsky S‑76D, and Bell 525 Relentless are twin‑engine helicopters aimed at executive/VIP, offshore, and utility missions, while the Embraer Legacy 500 and Gulfstream G280 are midsize/super‑midsize business jets designed for higher-speed point‑to‑point travel. On range, the helicopters generally cluster around roughly 450–600 nautical miles, with the S‑76D and H160 typically in the lower-to-mid part of that band, the AW139 commonly around the mid range, and the Bell 525 generally at the top end among these rotorcraft at roughly 600+ nautical miles. The jets are in a different class: the Legacy 500 is around 3,100+ nautical miles, and the G280 is longer-legged at roughly 3,600+ nautical miles. Passenger capacity also separates them: the H160 typically carries about 12 passengers, the S‑76D about 12, the AW139 often 12–15 in many layouts (higher in high-density configurations), and the Bell 525 around 16. The Legacy 500 is usually configured for about 8–12 passengers, while the G280 commonly seats about 8–10.
