I seriously believe that a part of what makes an anime Dub good is that they have believable names.
That's why people think the Big O and Cowboy Bebop dubs are good. They have normal names and the voice actors dont fail hard pronouncing the japanese names.
Detective Conan was a good dub solely because it wasnt Ran and Mitsurugi and all those weird ass moon names, but it was stuff like Jimmy and Rachel. Each mini character was steve or robert. Anne or Susan.
