Roggenrola or Drillbur?
I just started a new Pokemon Black game, and I'm making my way toward Wellspring Cave. In my Pokemon White run, I used a Krookodile, so I've never used either of these Pokemon or their evolutions. Which do you find better, the Roggenrola/Boldore/Gigalith line or the Drillbur/Excadrill family? Right now I'm leaning towards using a Drillbur, but I want to hear from you guys before I decide.
