I think watching dubbed takes the fun out of watching anime. It's called anime and not cartoon's for a reason. Just my opinion.
Then be a true hero and watch the raws!! Though for actual input I also prefer subs as well, mostly due to the faster release cycle as well as the opportunity to learn as someone who has studied Japanese over the last year. It helps build up some vocabulary as well as maintain an understanding of what I've already learned in class. Though admittedly as a fellow weeb I was watching anime in Japanese w/ subs long before I actually took classes for it.Personally, I prefer subbed because a) I love listening to the language, and b) It helps train my listening skills. Besides, what I find is that a lot of the time, dubs take away key parts of a character's personality even just through their voice and tone. Really a loss imo. That said, dubs are most useful to me if I'm eating and have to look at my food instead of subs lol. I have heard that some anime has a better dub than sub, but I have yet to watch any.
