Okok final verdict
I DIDN'T THINK IT WOULD BE LEVI, I KNOW I'M ALWAYS A SUCKER FOR THE MOST POPULAR CHARACTERS BUT FOR SOME REASON I JUST DIDN'T THINK I'D FALL FOR THEM THIS TIME
I still like Eren a lot
Like basically season 1 to season 3 Eren was tied with Levi, but S4 Eren... It's not that I
don't like him per se, but it's like, probably going into spoiler territory so-
he's a totally different character now. I know he was changing gradually throughout the series so it's not like a sudden change into season 4 Eren but likeseason 1-3 he still had some life in him and it was fun watching him work stuff out since as the audience we were basically working it all out with him, but in season 4 now he's just so depressing and serious and he's already seemed to work everything out by himself now and it feels like he traded his whole personality to go on ahead with his plans eheh. Now ofc Levi is serious too but not in the depressing way and unlike Eren he still seems to actually care about the people around him, meanwhile it seems Eren has pretty much abandoned Mikasa and Armin at this point. I don't dislike the new Eren and this is by no means criticism of the actual writing n stuff but rather he just feels like a completely different character now therefore my reasons for liking him in the first place no longer apply >.>
So to sum it up, season 1 through to 3 it was Levi and Eren joint top but season 4 Levi takes a much cleaner win so I guess we could say overall it's Levi
