I've been fortunate to fly to space on three different vehicles, and I'm often asked which one I prefer. It depends on the phase of the flight. For launch thrill, nothing beats the Shuttle. For a smooth ride uphill, I'd take Dragon, then Soyuz. Dragon wins on cockpit displays and docking — the softest docking I've ever felt. For landing, a Shuttle runway is still the most civilized way home. That said, I'd be happy to ride any one of the three any day of the week!
