Overall, Kerry Wood has had a better, career because he has pitched a lot more than Mark Prior. If both had stayed healthy, I might say Prior, but both have had significant chunks of their careers wasted because of all their shoulder surgeries. Remember, Wood had 20 K's in one game. He has more k p/9 than any other righty pitcher in baseball history. Prior did go 18-6 in '03, but he really hasn't done anything else.
