Veronica is the most boring of all of the sisters. Sorry for those who love her, but she has the personality of a cardboard box.
Even though I can't stomach all of the evil stuff very well, I would much rather play for Juliette even than V.
Sure, V probably plays an important role for the preservation of humanity and possibly in saving humanity's future with the expansion into other planets, etc. in the distant future... But still, I think I get more joy watching paint dry than reading most of her dialogue.
Alessandra on the other hand... Now that's a hottie.
