Which one should I watch, FMA या Brotherhood? Is there a difference?

The original ऐनीमे doesn't follow the manga, while Brotherhood follows the manga. I think आप should watch both. The original anime, despite not following the मांगा completely, is incredibly emotional, though it's also very dark as well. It's amazing in my opinion. Brotherhood is और humorous and less dark, but it's great as well! But yeah, in my opinion, आप should watch both. The और Full Metal Alchemist the better, right? <3

I won't watch either because I detest the art style, but I hear Brotherhood follows the मांगा while Hagaren (FMA) does its own thing.
