I think the only FGC I could claim to be my waifu is Akiha because of the bullshit playstyle I made for her. I don't really have an absolute favorite character in DoA; on a character/personality basis, I like Ayane, Leifang, Helena, Bayman, and Zack (yes, Zack). Kasumi also gets a mention for her backstory.
So far, Sat's looking good.
