I see B777 mentioned here several times. It's OK. But with 15,000hrs on type it pails to other, proper, non-FBW control aircraft.
Beech 200 Super Kingair. Best single pilot IFR aircraft ever.
Any AreoCommander would come second. 500 or 690. All fantastic.
And as much as l disliked the BAe 146 for over complexity, it did handle beautifully.
