A lot of the time if you want to get all the facts about a series right, you need to read the manga, because the anime just doesnt say everything that needs to be said.
And like afore mentioned, anime has pointless filler arcs. Ex. The fan/ratings killing never ending utterly pointless filler arcs in Bleach. How unfortunate. *sigh*
I mean in all seriousness, manga just has a lot that anime doesnt. Now, if the anime would follow the manga to the letter, (or very close to it) I would choose anime.
But as it is, I have to go with manga.
