I voted for my own seminary (Mid-America Reformed Seminary) because all the professors are ministers and have experience preaching themselves, the curriculum places great emphasis on preaching, and of course I know some fellow students who I believe are "good preachers." Perhaps a more objective way of determining an answer to the question in the OP would be to compare the number of classes offered that have to do with preparation and delivery of sermons.

"It is part of the calling of the ekklesia to learn to know the love of Christ that surpasses all knowledge and also to make known within the world of science 'the manifold wisdom of God' in order that the final end of theology, as of all things, may be that the name of the Lord is glorified. Theology and dogmatics, too, exist for the Lord's sake." — Herman Bavinck, Reformed Dogmatics, vol. 1, p. 46
