Rarity for me, because not only is she pretty, she is also fashionable, smart and clever (THIS IS WHINING!) I know sh's the best, cause she has the eyes to prove it.
Purple hair, the color of royal. Probably because she is as regal as princess celestia.
Excellent posture, both graceful and elegant.
Mare-ve-lous as a human as well.
Also, diamonds. DIAMONDS ON HER BUTT
