I like all of them! I like
Delilah, but I don't think it would age well. I can imagine it being really cute on a little girl but I don't think an older person would appreciate it. At this point in time I'd say that my favourite is
Lila, because after the Oasis song I have fallen in love with it. Also
Lily is getting quite popular where I live, and
Lilia and
Liliana would just get shortened all the time. So I like
Lila best because it is so pretty!
