The eternal sub versus dub argument has always been spergy.
All comes down to entertainment. Jojo for example is always gonna be a goofy, badass show. The sub packs a lot more emotion into many moments, this is based on tone and sound in general. I'm not a mystical nippon man, so I have no idea if its cornball overacting, but I like how the characters sound in Japanese.
The dub is fucking hysterical and amplifies the goofiness of an already goofy show. Its great in its own way if you don't have a huge stick up your ass.
Both are their own flavor of the same show. I'd say if an anime is worth watching twice due to differences in sub versus dub, that's a much stronger anime compared to others.
