I absolutely LOVE the Eden Speedy. It's gorgeous, and I think that it's so different than everything else! The Idylle is just too plain to me, and I'm really not a fan of the way it looks with the leather on the sides for the strap. Maybe it's because it's just an updated version of the Mini Lin which is throwing me off.
Whichever bag you choose will be great though!! You really can't go wrong with either.
