Wondering...Pour le Piano or Estampes

[odsum25]

I was listening to some Debussy today and discussing the pieces with a friend and fellow musician. Which do you personally find more difficult, Pour le Piano or Estampes?  I find that Pour le Piano fits right under the hand and comes naturally to me, while Estampes is much trickier to get across, with the exception of Jardins Sous Le Pluie which is a definite nominee for a piece that sounds much more difficult than it really is.  The Estampes just cause so many problems for me, but I'm going to have to think more about exactly why...
