I literally stayed up late to watch the original FMA and bought the first book when it came out. It was the coolest thing on TV at the time. After reading all the mangas (AND THE FINAL BOOK! FINALLY) and watching Brotherhood on Netflix, I really dont have an opionion. The original FMA was great, but after the first half didnt follow the manga. They realized their mistake, and decided to rerelease the anime upon completion of the Manga. Seeing as they reatained all but Al's voice actor, I have to say thats pretty incredible. Brotherhood is definently alot more twisted and grotesque, but then again, so is the manga.
