FMA original anime was too boring, it was as if it was aimed at 12 year olds, and the reason brotherhood was rushed (which i agree with you there) is because they had to fit alot of chapters in really fast (i dislike how they completely skipped the storyline of yoki and only touched on it 40 episodes later, but turning it into a joke) so i prefer brotherhood but that may be because i read the manga first before anything else
