I used to love it, but now I infinitely prefer Dahlia. Tallulah is sounding stale to my mind and I do like a bit of seriousness to a name now that I'm actually naming babies. I used to like all of that rash of insubstantial names - Lola, Lulu, Coco, Pixie, Tallulah - and for sure they have charm, I just wouldn't use them.
To see how I got from Tallulah to Dahlia, I initially thought Delilah was nicer than Tallulah, then Dahlia nicer than Delilah.
Gosh did that make any sense?
