It's getting hard to choose.

Rapunzel has been around long enough that enough people may recognize her (plus her hair is a dead giveaway). Elsa is known through shear overexposure and non-fans may only think of her as that "Frozen chick."

People might not know of the movie Tangled, but the story was well known long before the movie came out even by non princess fans.

Everyone knows who Elsa is because of Let It Go

Frozen is new and sometimes people don't know Elsa.

Sad to say it, but, out of these princesses, Rapunzel is...

Elsa? Really? I thought that she will win this cause every kid/adult knows her 'Let It Go'. I've read a list about favourite DPs' merchandise and Elsa is the first, beats Cinderella, meaning many people buy her merchandise.

Rapunzel is losing her popularity since Anna and Elsa arrived.

How is Elsa not winning this? Frozen is now the #1 animated grossing movie of all time, and almost everywhere you go, you'll see something Frozen related, or even little girls singing Let It Go.

I love Rapunzel, but suddenly she isn't so popular since Frozen.

I guess she is the least know of these.
