Manga is nice if you want to catch up on animes that have been going on for a long time or if there is an anime you're watching that is based on the manga but got cancelled before the ending you can then find it by reading said manga. Also forgot to mention a lot of the ties the manga is rawer in its detail and is a lot better than the anime itself so if you have a few animes which you have seen I recommend you start a manga collection by reading manga on animes you have already seen.
