Agreed! I've only seen about a little more than half of Brotherhood (everyone said it was too rushed in the beginning), and while I too really enjoyed it, everytime it diverged from the manga I liked the manga more. And Arakawa's own art is so good. ♥

It really is a masterpiece. It has to be one of the two best complete shonen manga that I've read, the other being Barefoot Gen (which is a horse of such different colour it's probably meaningless to compare them).
