Right now, we don't really know what their stats will be like, or what stats would even be most desired. So I guess this is just about looks.
Personally, I'm thinking I'll go with a Lalafell. I quite like the Lalafell. But I don't know if I'll go with Dunesfolk or Plainsfolk. What about you, EoFF?
(SPOILER)To be honest, I'd rather choose the Miqo'te, but there's no male Miqo'te.
