First time always dubbed. I want to take in the visuals and not miss anything. Later on if I rewatch and I hear it's a bad dub because the meanings are wrong or things are missed, then I'll watch sub to take in more nuance of the writing.

Either way I find there are cultural memes that simply never translate and sometimes the dub, while less accurate, makes more of an effort to translate the memes into something similar that I can understand better.
