If you have access to Kilian or Nasomatto, please consider Love & Tears or Nuda, both of which I rate higher than these two while being jasmine soliflores. If orange flower is more important, consider Vero Profumo's Rubj Eau de Parfum.
That being said, if I was buying for someone whose tastes I didn't know and had to choose between those two, A La Nuit is the safer choice. Pretty much straight-up jasmine.
If I was buying for me from those two, Olene. Olene is still the most searingly intense white floral I know.
