Fluttershy fits better with the whole, “innocent, most beautiful in the land” role of Snow White. Even Rarity herself stated that she doesn’t know another with more beauty and grace than Fluttershy.
I thought it was more of a joke series? Seeing as Twi got screwed over in the comic strip before with her bad dancing. Now it was Rarity and her popularity. XD
He kind of has a point though. Rarity is almost always dead last or second to last in the popularity polls.
I don’t care about the polls however, I still love Rarity and think she’s indeed the best pony.
