Checking my log book, first flew a fenestron tail in 2009, last flew a non-fenestron tail in 2016 (B206 L4), since then only fenestron.
Have experienced the "loss of angle of attack" effect mentioned by Craab, have learned the non-linear pedal input and have seen the torque spike it creates. Also experienced the "tail the size of a barn" (not just the door) effect when yawing through the wind.
Never once experienced an inability to control the tail, which I put down to good training and being ahead of the aircraft (I did throw-away one approach and go-around due to (upon reflection) being behind the aircraft in yaw control as I bled speed, but I am of the view that this is what I was trained to do). Coming back the second time, no issues.
