I'd say you'd have better overall "success" if you started as a strength athlete (powerlfiter or Oly lifter), and then went into bodybuilding. By starting as a bodybuilder, you'll have a large amount of fluffy muscle which isn't as strong as it could've been, had you started training for pure strength sooner (though, that's a topic of some debate).
Franco Columbo, Big Arnie S., Dorian, and Coleman all did some competitive powerlifting before walking down the speedo path. Sergio Olivia, Tommy Kono, and Christian Thibaudeau began as Oly lifters.
I'd disagree with that. The bros at Westside have said over and over again that a bodybuilder's bench press exercise is not the same as a powerlifter's bench press exercise. The bodybuilder is generally a more diagonal movement, in order to work the chest. The powerlifter version would be straight up and down, using the tris. And I don't remember the last time Flex magazine included box squats in a "Tree Trunk Leg" article. Plus, most Fitness mags consider the deadlift to be a "lower back exercise".
