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

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

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