Could you specify what you consider "the best"? The best according to what? The game in my opinion is very well made in a sense that it plays differently but equally captivating depending on the kind of character you choose to play.
I have checked out several different origins and must say I wasn't disappointed in any one of them. Well, I didn't play the more extreme ones yet, like the bimbo or Broodmother, so I don't know about those. But then, I tend to role play the characters I choose so I try to optimize the play to my understanding of them.
While I would agree with the meaning that Gamine is very consistent with the setting, you have to remember that your original character started before the pandemic, when the world wasn't so screwed up as it is now, so in my opinion it's not necessary "the best".
I liked the "Gym bunny" very much. She is also well integrated since you are enrolled in the dancing class and there is a lot of fitness based content.
