Don't worry, today was a payday so I have about 4000 more reasons to consider Q400 the best aeroplane in the world. I concur with all your points and advices on her, however I have logged just a bit north of 1700 hours since getting Q400 endorsement and it came after spending 2600 hrs in ATR 42-300 and 1200 in A319/20 so IMHO that makes me qualified to make some comparisons. Not all of them turn out favorably for my beloved, though. Anyway,given the same T&C, I would rather pick Q400 over ATR because of: 1.performance 2. APU 3. nosewheel steering connected to pedals 4. HGS.
