I don't know that any of them will develop into something special. The best of them will probably be the Leoville Barton, Grand-Puy-Lacoste and the Haut Bailly. I've had the d'Armailhac and scored it 90 points. The best deal is probably the d’Aiguilhe.
Have you considered Haut Bergey, if your tastes align more with Parker this could be a very special wine (I think he gave it a 94?). It is still available here for about $55 I think. On the other hand, if you like Decanters ratings, look into the Dauzac which got their highest rating of 5 stars. It sells for $30. Here is a thread about the Decanter reviews.
