I prefer in paper comic form so I can read it in my leisure time, the story are usually better and more detailed there, but if we are talking about anime in the form of animation then its DVD because I can pause and rewind if I miss something, usually the subtitle because its too fast and most of them still in japanese language which I don't understand, and without needing to get a delay and waste time from add, since I live in third world country where internet connection are fickle and lag a lot especially when watching video online.
