Same difference to me, it's like asking if you like Vanilla or French Vanilla !
They're both great choices !
If you want a less expensive option for a damier pochette now you can do the damier Trousse Makeup, it's shorter in length but a little wider at the base so it fits about the same.....it's almost $100 less than the Navona too I think...I love mine and barely see people carrying. This was the option for a damier pochette type bag before the navona ever came out....
