Aniplogs: ''I'm not too sure of how credible the data is but according to anigaman blog Jean wins in terms of popularity over Eren by a small margin from votes taken from different countries. Being a big fan of Eren because of his personality I'm quite skeptical on how Jean could win as he's more of a scared douche fag and doesn't prove anything yet in the anime.
The results were casted from 40 countries with a total of 48298 voters. I'm not much of a manga reader so probably a fraction of the voters have read the manga already which showed an interesting side of Jean.
Below is a detailed diagram of results from different countries.''
