Aside from wins, which 300-win pitcher is the best?

Of this list, I would have to go with Warren Spahn. It's certainly not Nolan Ryan, one of the most overrated pitchers of all time, despite what Don Antonio and some others think. Interestingly, there are four non-HOF pitchers on this list-Glavine, Johnson, Maddux and Clemens. Depending on the voters, Roger Clemens may become the only member of the 300 win club not to be enshrined in Cooperstown.
