Because my first church was an urban church in a multicultural community this white boy from the backwaters of Washington State had to learn a completely different way of communicating. My preaching "style" needed to be leavened by the communications styles common to the folks I was trying to reach. As a result, over time, I adopted some of the characteristics of black preaching. I even got so I could manage a bit of the "rhythmic" movement between preacher and congregation with things like Amen, preach it brother, come on, that's right... etc. My best sermons, the ones people tell me they liked the most were ones that involved a lot of congregational response during the sermon.
After 13 years of learning how to communicate in that environment I moved to the pretty vanilla suburbs. My congregation is filled with scientific/engineering types who live in their heads and except when I prompt them don't make a sound, and like it that way.
This meant that I had to do some major gear grinding to change up my style of preaching. Much more "teaching" with more overt exegetical work and even a fair amount of teaching people how to interpret the Bible. My best sermons, the ones I get the most response (after the service) are ones in which the congregation gets very, very quiet.
Still preaching the word but the style has radically changed to fit my congregation. One of the things I say when I teach preaching is "The Word determines What you say, the Audience determines how you say it."
So what is your preaching style and why, if you are a preacher. If you are a lay person what is your preferred style?
Note - talking about us normal preachers. The "star" preachers are so good they are kind of in a category by themselves.
