Before we continue our little list, some honorable mentions:

Cotton Sky - I really like her mane.
Daring Do - I don't know why, but I love her voice.
Flurry Heart - most unused potential. I imagine her as a future ruler, with a conflicted personality.
Lily Longsocks - stronk.
Twilight Velvet - best mom.

And now, the top 10:

#10 Cutie Mark Crusaders. Good depiction of children, who are enthusiastic and eager to do things, sometimes they mess up, but their hearts (as strong as horses) are in the right places.
#9 Zecora. A fine character is she, the mysterious zebra who lives in the Everfree.
#8 Sunset Shimmer. I think it's the combination of appearance, personality and voice acting, that makes me feel that there is some kind of 'warmth' emanating from her, if you know what I mean.
#7 The Great and Powerful Trixie. Undoubtedly the greatest pony who ever lived.
#6 Starlight Glimmer. What I like about her is that her personality is not easily defined by one or two traits, like most of the other characters. Also I love her nervous laughs.
#5 Maud Pie. Relatable, as I express my emotions in a similar way as her (mostly by not doing it at all). Also I love her sense of humor.
#4 Twilight Sparkle. Highly relatable, as I'm a studious and socially awkward person myself.
#3 Fluttershy. Another relatable one, because I'm a shy person. Also the embodiment of cuteness.
#2 Celestia and Luna. I put them together to avoid taking sides in the debate, which one I like more. Beautiful and majestic princesses with interesting personalities, what's not to like about them?
#1 Marble Pie. Cute, charming, mysterious. Best pony.

PSA: If your favorite characters are not in the list, it doesn't mean I don't like them, they just didn't make it to the top 20. I like most of the characters in the show.
