It's fun when I find still running anime I like, because I can watch it from the start like everyone else.

For animes, I prefer the finished ones. For mangas, it doesn't really matter tbh.

I'm currently watching Karneval too, which is still running, but i prefer older ones, because if i like the series, I can get shirts, coffee cups, and posters....

I don't really have a preference.

I watch both, but if its still running i tend to forget about and don't come back till it's finished airing XD

Although I really don't mind, I watch both and when it comes to currently running anime it always keeps me on my feet because I'd have to wait to see the next episode opposed to a finished anime where I can watch all the episodes any time I want to..still really enjoy both.

Same with Dewheart.

It's too troublesome to wait for new episodes, I prefer the finished animes since I can watch how much I want.

I like to watch an anime when it's finished
But there are exceptions like Naruto and the manga of Skip Beat
