i use to actually watch the anime rather than reading the manga, but i believe that the manga is way better compared to the anime. Because just like in regular books that are re-maked into movies they take out a LOT of the good stuff from the book in order to fit the main point of the book into a 1 hour and 30 minute production, like twilight for instance. I'm not a fan of the book, i'm simply just using it as an example.
I actually realized that reading the manga was better than watching the anime THIS YEAR XD
but yeah, there are though a lot of great series that still are mangas and are not animated, so it can be a good opportunity to discover a manga that would suit your likings

or something like that...
i hope what i said was understandable in some way ^^;;;;;;;
