Male Miqo'te from day 1 [my day 1, not ARR's]. The body shape is great (wish I looked that good when I was younger), animations are cool, and that 'chuckle' emote is perfect.

I've tried others, but didn't get a look and feel I like, except for the Lala monk I made as an alt.

For a race change, you get two free bottles of Fantasia while leveling up. They can help you change to another race in Eorzea.
