I love the anime. I like the characters, the story, the artwork and just about everything about it. I've yet to find any of the Manga, but I am interested in it now thanks to the anime.
That all said, I highly recommend you view the 2009 version over the 2003 one if you want a closer adaption to the manga. That isn't to say that the 2003 one isn't good, believe me, at the time it was pretty damn good in my opinion. The only sad thing about the 2009 one is that the English adaption is incomplete (Only 27 of the 64 episodes have been done in English) and since they seem to rush through the background in the first 15, it doesn't leave much.
In short, I hope you like Japanese with English Subtitles if you or anyone is thinking of watching the second series.
