I personally prefer to read the Manga over the Anime since time to time the Anime has been filled with useless fillers and had important pieces removed. :P I currently have about 40-50 ongoing subscriptions to manga that get updated regularly and have finished just about the same amount if not more. I have watched anime since ones like Gurren Laggen are better watched then read, however as I mentioned above I prefer manga overall. Favorite series? This keeps changing, I like different series for different reasons but overall one that held my addictions the best would have been The breaker and its sequel The breaker: New waves.
