Trixie not one of my favorites aside, the right side has better hooves, cutie mark, and expression (including her eyes); the left has a better horn, mane, and tail. Plus, in all honesty, I like the color on the left better though the right is closer.

I love that top-right pose on the 2014 version. Fits the expression perfectly. :3
