I watch dub because I'm too lazy to read. I only watch sub with there isn't any dub available. As for the argument of not getting the full experience, I can only see it that way when the anime is centered on Traditional Japanese folktales, mythology, or history such as Genji Monogatari Sennenki or Shōnen Onmyōji. But even still I'd try finding the dub if available. Also not all dub is bad.
