Unfortunately, I like both of them, due to how different their personality they both have. I cannot easily pick-and-choose one or the other, as one has a personality that I enjoy that can be related to one of my characters, and the other one who I also enjoy that can also be related to one of my characters. I love Sonia for how calm and kind she is, as well as having this cute, but sexy look. Malice has this sort of personality that seems to say that she is both experienced in well... most party-like as well as the more dirty type of partying types out there, which I quite enjoy as well.
I cannot really pick and choose which of the two in reality. I really do love both and it is quite too difficult for me to pick one or the other. Don't get me wrong. I'd love to hang out with both of them if given a chance, but it's just... too hard to go with just one of them.
