Just to generalize, your Presbyterians bring closely reasoned Biblical scholarship and excellent preaching (I don't think you can get much better preaching than the best Presbys, as far as reasoning, persuasiveness, and a dignified delivery), the Baptists can organize the business/committee end of the church better than anybody around, the A.M.E.s preach with fire and enthusiasm, and the Episcopalians can handle the music appreciation (they're not fit for much of anything else, I know, I used to be one.)
I’ve also heard some good sermons by Baptists.
I’ll have to defer to your “inside info” on the others. :o)
