MD Good.
Flew the DC-9 30 and 50 for three years as copilot followed by fifteen years as captain on the DC-9 and MD 83, they were my favourites, beats the 737NG, and the wide body Airbuses I currently fly, I always try to think that the best aircraft around is the one I currently fly, but the DC-9 and MD 80 are the best "pilots aircraft" ever. I did fly the L1011 for a year, and that was one great aircraft. The Buses I fly now are no where near to the McDonnell Douglas products I cut my teeth on.
