Manga tends to be very interesting, so you will have an easier time remembering the sentences. There is one downside though - you have to at least learn hiragana to be able to read it. The books usually have several example sentences, as well as a bit of vocabulary you can learn. I already recommended one book I feel is very useful to anyone learning Japanese. Manga allows you to look up each and every word in a dictionary.
Anime does offer an advantage, however.
You don't have to know any of the Japanese written language to be able to write down words and sentences you heard.
