For me, I always like manga more than anime. The main reason is that since animes are produced based on the mangas, they can be late by about 1 year of 6 months. Because of that, the stuidos are putting in fillers to wait for the source to catch up. Personally, I don't like anime fillers because I cannot feel the author's touch at all but with mangas, we don't have that.
The other advantage of reading mangas is pacing and speed as reading mangas is generally faster than watching animes. I think on average, a 20 minutes episode cover only two chapters of manga that you can read in less than 10 minutes. That is why it is easier for me to pick up new series and read them if I focus on reading mangas.
Finally, with mangas, I think the artworks is more detailed than in the anime and therefore I think the images are cooler in mangas even though they are not moving.
What do you guys think?
