Even among these five private options, there is no clear overall winner by price-point or features. Each may very well be the appropriate choice depending on need and intended use. The XRS and the G650 are as close as they come in terms of ability and size. While comparing the two, the G650 is only about fifteen-percent better with a heftier price tag. If you’ve no time nor the interest to conspire with Mr. Lucas about something new and space age, any one of these private jets will draw extreme envy and awe no matter where you land it.
