I love them both so much so it's really hard for me to choose so I had to say both even though deep down I prefer Elsa a biiit mooore.. I feel a strong connection with her character (and when she sang Let It Go, omg that song just hits me).
Anna is adorable, strong, peppy, funny, determined, and complex like Elsa and oh-so-lovable but I still have to go with Elsa ;v;..even though I chose both. 6u6
