Usually I stay pretty loyal to whichever branch of the fandom I came in on. XD; And for most Japanese fandoms, I've seen the animes first. I know the mangas have different storylines and are more generally preferred, and sometimes I do prefer certain things about the manga versions, but they're also usually gorier. Heh. Like there's so many beheadings in Rurouni Kenshin, manga version. O__o And Kaoru seems even more abusive, which is one of the traits I already didn't like about her in the anime. XD; Mangas usually have more swearing in them than their anime counterparts, which I frown upon. And sometimes I just like what's done with the characters in the animes better. Like the Doom saga of YGO. It's anime-only and I'm loving it. I do appreciate mangas (heck, without mangas, most of the animes I love wouldn't exist!) and I even collect a few titles, but overall I do prefer anime in the end.
