Sorry I didn't notice this question beforehand, we are going with Bertolt Hoover. In his talk page, a long discussion was held between several members. In the end it turns out that Kodansha, where the spelling was taken from, has the okay from Isayama on the spellings. With Isayama being our highest source, anything he ok's becomes official. In Eren's case, on Attack on Titan's official twitter account, they posted the official English spellings for Eren, Mikasa, and Armin's names. That being said, thank you for your interest in helping edit this wiki.
