Dassault Falcon 10x vs Gulfstream G650er vs Gulfstream G700 vs Gulfstream G800 1

In category, all four are ultra‑long‑range, large‑cabin business jets, but the Falcon 10X is positioned as a new‑generation flagship with a particularly wide and tall cabin, while the G650ER is the earlier long‑range benchmark and the G700/G800 are Gulfstream’s newer flagships emphasizing cabin comfort and efficiency. On range, the G800 is generally the longest‑legged at about 8,000 nautical miles, followed by the Falcon 10X at roughly 7,500 nautical miles. The G650ER is close behind at about 7,500 nautical miles, while the G700 is slightly shorter at around 7,750 nautical miles, trading a bit of maximum range for a very large cabin and high‑speed cruise capability. On passenger capacity, typical configurations for all are around 12 to 16 passengers, with maximum seating commonly advertised in the high‑teens. The G700 is often presented with the highest maximum seating (up to about 19), while the G650ER, G800, and Falcon 10X are typically up to about 18, depending on layout.
