Why Alan Davis? Because he's capable of drawing different face and body types. He also understands that women have hips, not just tits n' ass.
Really, any of your typical cheesecake guys (Cho, Linsner, Hughes, etc.) only draw one woman with one face and body type. It doesn't matter how good they are at drawing everything else, and usually they are pretty good at drawing other stuff, they can only ever seem to draw a single woman regardless as to who the character is. It's sad, really.
