Of the jets, in order (best to worst): BAe146, Westwind, 737-300, 737-700, A320
Haven't flown any turboprops.
Of the piston twins: Baron, Seminole, Navajo, Partenavia. Never flew a Commander series.
Of the singles, the Pitts surprised and delighted me. Haven't flown a chippie. I prefer Pipers to Cessnas for handling and training, but the Cessnas are more practical in the real world.
