These days, I pretty much watch anime as it airsor the day after, so subs are the only option. It's fine, since it's my preferred option. I'd much rather hear the original voices and stuff because I feel a lot is lost in dubbing.

There are some high quality dubs out there with really good casts, so there are a few anime I've only watched in dubs, like Samurai Champloo and Cowboy Bebop. I was satisfied with their dubs and never felt the need to hunt down the original. And sometimes for an anime that has really complicated science and other concepts, I'll watch the dub. So I've watched all of Ghost in the Shell in English. It was just way easier.

But again, I lean heavily towards subtitles. I just like them better.
