I would go with hitting but it all depends where you are in the draft (where you pick). If 1-7 you should get a very good hitter like Vlad, Albert, A-Rod, Beltran. At number 8 people seem to tend to pick stud pitchers such as Johnson, Prior.
There are some many pitchers, you might as well pick up a great bat in the first rd.
