They're both really good. First is nice since i thought the movie had a really unique ending to it that i didnt think about. It was pretty cool how they intigrated our world into theirs. Still i want to say brotherhood is better. I thought it story was more suited with the anime. I felt pieces they laid out at start were a better fit to it. Also like people said above Brotherhood follows the manga which is the "original" story so to me brotherhood is considered more "original" even though anime was released later, it's story exsisted before.
