Chopin Ballade Confusion

[virtuoso]

i am playing all four ballades at the moment, and might I say that the 1st and fourth are by far the hardest.but the hardest is the fourth: technically, emotionally and interpretively! The 1st is hard, but not as tricky as the 4th.  Then comes the 2nd which is also difficult and then the third.  But if you notice, it is the coda of all of them, which makes the pieces so hard.
