Personaly I prefer Adult Maria, but I voted for the HD because it's really a nice reworking of her original design, and I have to give it respect for that alone.
I like the seond design as well, I really can't see why so many people hate it. There is this big misconception that it's a tomboy work. Well it's not exactly the case. Back in my native Portugal, and not just there but in several Eurpean countries they have traveling Horse Performers, the performers wear an old style of dress from the 1700's or 1800's depending on the nation of origin. Maria is pretty much wearing horse riding clothing from thattimeperiod, which mkaes sense with her being an animal lover, not to mention she's fighting monsters... a dress would just get in the way.
Oh and yeah, Judgement Maria has no place on the list and I'm glad it was left out. The design is just disgusting...
