I honestly trust overdubbing more than fansubs. Subs are usually direct translations and lose a lot of meaning and feeling because of it. A lot of the things people say are idioms, and when there's a direct translation of that, it goes over the heads of anyone speaking the language it was translated to.
Professional dubbers are professional translators and professional writers who know how to make something sound good in a different language. Of course this is not 100% true and the voice actors play a big role in making it sound good. But all the subbed anime I've seen just 'sounds' odd when I read the subtitles. It definitely sounds like someone is directly translating the Japanese word-for-word and it comes off as having bad grammar.
If someone translates something literally first, then tries to subjectively find a more suitable idiom or word for it, it sounds much better and is more relatable to the english viewer.
Take Shin Chan for example. If that was directly translated, we would never understand what topical references they're making to Japanese culture. But when they replace names with Brittany Spears or Paris Hilton, all of a sudden we understand. Of course that's not the most literal example, but hopefully you get my point.
