Why didn't Sevendust blow up the same way Korn or Limp Bizkit did?

I to this day cannot figure it out. They are as talented or more talented at every instrument (except probably b), their songs were every bit as catchy, and they put on a better live show. Does it have alot to do with the lack of radio support? Perhaps because they didn't have some kind of lousy gimmick? What do you think?
