Freedom, and challenge. Flying an automatic Airbus on a regular route has its challenges, but it could be argued that they pale in comparison to single-piloting a turbocharged, pressurized light twin through bad weather to an unfamiliar airport. Aboard the latter, you're dealing with a cockpit forest of throttle, mixture, prop, turbo, cabin-air and cowl-flap controls, dangerous handling qualities if one engine fails, and an analog autopilot, compared with the big airliner's two power levers, two pilots, and near-totally automated, computerized operation. Indeed, two things come as a surprise the first time you fly a big airplane: It's way more stable on the approach to a landing than is a little one, and its size is really only apparent to a pilot on the ground, taxiing through close quarters. In the air, you're aware only of the stable, automated cockpit, and this is why flight simulators work so well.
