1 Anya. 2 Olivia. 3 Cleo. 4 Lola. 5 Amira. 6 Leila. 7 Julia. 8 Grace. 9 Nia. 10 Margaret.

At the same time, Julia is the most popular character in the discussions and people constantly ask about her scenes, as TDavy said. The same can be said about this topic - there are a lot of questions about Julia. But even Amira is ahead of her in the rankings!

One could say that Julia's fans truly love her and are willing to ask about her (she's the mom they want a patch for) even though they are in the minority.
And Margaret is at the very end.
Remember how Larian shared statistics on character creation in the Baldur's Gate 3 editor? If you collect all the players' choices and combine them into one, the result would be an ordinary person. Not a horned demon, not an elf, but a simple man.. I think people tend to choose the golden mean.
Julia (yes, this is my favorite character) has large breasts (#1 Breast in the NLT Universe) and her mother's age. This is something that can push others away, and I understand that. It's like an expensive wine that not everyone can appreciate, preferring a bright but dangerous cocktail.
