All the 320 family aircraft can be a handful in a gusty approach - it's not unheard of to be deflecting the stick all the way at times, which unerved me greatly to begin with.
I wouldn't disagree with you about them being a handful on gusty days, and would personally prefer them to go to direct law in roll with the gear down, but re the above, don't forget that the stick is demanding rate of roll/pitch and not surface position until the stick is held there long enough. Therefore full sidestick does not equal aileron/spoilers at the limit of their travel.
