The vast majority of people who have watched DB have taken issue with Toriyama's version of Goku, Z and onward. From all over America, to Europe, to even most of Asia, as Goku isn't ever the #1 most popular character in Japan, Vegeta takes that crown.
The characterization was fun during the early portions of Dragon Ball but as the manga progressed, Goku's morality strengthened.
People have shown examples in this very thread, the Red Ribbon one being a prime example.
Heroic Goku is actually a two-dimensional character, rather than the one-dimensional garbage current Goku is, that Toriyama loves so much. He only loves that version of him because it's easier for him to insert his shitty gags that way. Vegeta's character has actually progressed since his introduction, which is why he's a far superior character and his fans are much more respectable. Goku is barely a character anymore, just a glorified plot device to drive-up power levels.
Tardku and his fans are the worst fanbase of DB hands down. Nobody else can even compare.
