Hard to believe either cabin is acceptable--quite a wide difference. The G5000 does burn more gas, it cannot be any other way with 50% greater TOGW. The G5000 is built like a tank, cruises at M.85, goes another 40 minutes at a speed the F900 cannot cruise at all. Falcon probably has better OEM support, or at least the reputation is that way. Waiting time for delivery might be a decider, too.
