How about watching both so you can have your own opinion? That would be my general recommendation for everything. I guess the old Hellsing anime would be a good example of the same thing. The 2003 anime is enjoyable and some of the early parts are better in that version. Regardless of what people say, it was worth watching back then and there is no reason for that to be different now. Ignore what everyone else says, they are all faggots, and wrong. Don't waste time on that, they are both worth watching, so just do it. Even if you think it's complete shit, then you will at least know what you dislike about it and why, and will actually have experienced it. Most people on the internet that are too eager to spread their bullshit haven't actually watched the anime that they talk about, they are just regurgitating what they heard from other people that probably haven't watched it (and that were possibly not even born/not old enough to be watch it in 2003 and have barely watched any anime at all).
In fact, Brotherhood is so close to the manga that if you already read it, the 2003 version can arguably be more interesting just because it's really different and you haven't seen it before. Having a different version of something tends to be more interesting to me nowadays than accurate adaptations. Original material has an inherent value that something that attempts to replace the manga can't have no matter how good it is. And really, if you enjoy something, you should check out every version out there since they will always at least feel somewhat different.
