Anime is shit and cancelled shitty, especially the english dub which is extra shitty. Manga is ongoing and awesome.
Soul Eater has less comedy than OP. Soul Eater has gotten way more serious. It's like life. It gets more serious as more serious things unfold. Soul Eater has comedy in the beginning, but it's only a hook. It now places it well.
Soul Eater is manga if Tim Burton wrote manga. I love it. Soul Eater has it's own tone and isn't in the same vein as Naruto or One Piece where they have a goody character who loves food and is stupid. Black Star is somewhat like that, but he's matured so much, he's Black Star, not what some may consider a copy. So, yeah, it's not like Naruto and OP, it's itself. I think you'll enjoy it for having some qualities like those mentioned, but like OP is OP and Naruto is Naruto, Soul Eater is Soul Eater.
Give Soul Eater's manga a try. It has 100+ chapters and the artwork changes/finds itself midway through. It goes from beginning sorta generic to being true Soul Eater. The author even said so, saying the anime's style influenced it, but it's not like the anime. It's all kinds of insanity and looks so great.
100% recommend.
