My thoughts on manga that I've finished reading.
These are the mangas that are /far/ more enjoyable than their anime counter-parts (in my opinion, that is).
Manga I have started adding to my collection but haven't finished collecting all the volumes yet. In the order of most to least collected.
The Dreaming (OEL)
Princess Ai: Rumors from the Other Side
I think Black Butler is classified as shounen, so that's why it's on this list. These are series that I have either finished or read enough of to rate. These are all just my opinion.
