I had always heard that Baccano! was better in english and we even watched it like that in club once. But when I then re-watched those 4 eps in jp it was a lot better and that is when I started to question how much people favor their native tong when listing to something that is good enough. I have found that in most cases the voice selections in the original language better match up with the characters so much so that not having them dramatically impacts the characterization itself.
