Bell 525 Relentless vs Dassault Falcon 8x vs Embraer Legacy 650 E vs Robinson R66

The Bell 525 Relentless and Robinson R66 are helicopters, while the Dassault Falcon 8X and Embraer Legacy 650E are long-range business jets. In category and mission, the Falcon 8X sits at the top end as an ultra-long-range trijet designed for intercontinental flights, whereas the Legacy 650E is a large-cabin jet optimized for long-range executive travel but typically shorter legs than the 8X. The Bell 525 is a modern, high-speed super-medium helicopter suited to offshore, corporate shuttle, and utility roles, offering far more point-to-point flexibility than jets but at much shorter ranges. The Robinson R66 is a light turbine helicopter aimed at private and training/utility use, with the lowest performance and capability of the group. For range, the Falcon 8X is longest at roughly 6,450 nautical miles, the Legacy 650E follows at about 3,900 nautical miles, the Bell 525 is around 560 nautical miles, and the R66 is roughly 300 nautical miles (varying with fuel reserves and load). For passenger capacity, the Falcon 8X typically seats about 12–16, the Legacy 650E about 13–14, the Bell 525 around 16–19 depending on configuration, and the R66 is usually 4 passengers plus a pilot.
