I know.

I haven't read all the manga, but I've read enough to know they follow the same basic plot.
As for dubs 'sucking', I can say that generally it only sucks (at least for me, I actually like dubs and a lot of the voice actors in them) if you watched the sub first. An example for me is Attack on Titan; I watched it subbed, but then the other day I tried to watch the dub and even though I love the voice actor for Eren, it was awkward to watch. The same goes for Fairy Tail; I started it in the dub, but then I got to the part where the dub stopped, and I tried the sub but just couldn't handle it because it sounds strange.
