Well, firstly, "greatest" is not necessarily "most beautiful". And I guess that Luthien doesn't count as she isn't alive anymore.

Interesting quote it is! So is she even more beautiful than Arwen? How can this be, if Arwen is the likeness of Luthien? Or is Arwen excluded because she, until he end of the third age, didn´t decided to what race she wants to belong?

Arwen's beauty was like an echo of Luthien's. That's how I see it. And they are both beautiful. Beauty is a thing of opinion, and there were some disputes *coughGimliandEomercough* .
