It's true that they're all saiyans trained to kill, but the difference is that Vegeta and Nappa were the villains of the saga, while Bardock and his team were the good guys of the movie. They weren't actually good guys, but from a storytelling point of view, they kinda were... every story needs its heroes and its villains, and in that case Dodoria and Frieza were the villains.

Anyway, I'm not sure I understand Itsover90000000's question, that Bardock isn't listed as Extreme on his Wikia page.
