Zeste is my least favourite of the citrus creeds. I find it a little feminine. I recommend Bois de Cedrat, Citrus bigarrade, or Acqua di Parma colonia over it.
Neroli sauvage is absolutely fabulous, citrus with amazing (low sillage) long lasting sandalwood underneath (search for threads on this).
Orange spice is a strong frag true to its name (i.e. orange and spice). In my opinion it is a winter frag, its quite heavy and not really a summer citrus.
Himalaya is very good too..
Maybe try and find someone who could help you try a small amount before buying .
