FMAB goes deeper into the story and takes some things out of the story.FMA was just a reproduction of the manga so when it became really popular the author decided to change the story and make it more interesting.

One difference is the cast Aaron was Al in the original while Maxie plays Al in brotherhood. The artwork is also different, in brotherhood they're more... roundish. While the original seems more... detailed sort of.
