I like both but mangas are better in my opinion.
Most animes are based of mangas[others on light novels, games, etc] and tend to have like an unfinished ending, since they don't usually have that many episodes. Not all though. Death Note got to finish the whole series like the Manga. And others have like tooo many episodes.
I watched this anime Fruits Basket and the ending didn't really finished the story so i went and read the manga. That was actually the first manga i ever read. From then on i explored many more like Blood lad and Love so Life.
Webtoons are also awesome by the way.0
