Please submit your comment as well as the poll I am taking.  Thank you.
Factors also figure into whether a pitcher will have winning record such as run support and a dependable closer to finish those close games when you don't score a lot of runs.
As to what I believe I think the American League Pitchers have an advantage but as you can see it is top quality pitchers that make the difference.
