Depends on it-regarding my favourite manga-One Piece-I prefer the manga, 'cause it's simply better..think there's 更多 action,more suspense,more fun..and I can't get enough of Oda's style!*____* Adorable!=D hm..but the're anyway some shows I like better 或者 at least as much as the manga..but strangely it doesn't wanna come to my mind now XD I'm sorry u-u
depends if the 日本漫画 is shounen then i don't like it but if it's shoujo then i like it and with 日本动漫 it's vice versa the shoujo 日本动漫 are too boring i mean i can go to sleep but the shounen 日本动漫 are awesome so it depends although i sometimes hate shounen 日本动漫 cuz they leave out the important stuff.
I like both 日本动漫 and 日本漫画 but I think I prefer animes 更多 since I spend 更多 time in animes than in manga. I usually read the 日本漫画 because I want to know the story faster 或者 the 日本漫画 is longer than the anime.
