I'll take teaching over preaching any day of the week.
Give me some good, solid, hermeneutically sound teaching and I'm happy.
You don't HAVE to sound like you're having an asthma attack to get a message across...

I still think it comes down to preference, though, and I think that's okay.
I don't think anyone should dismiss a preacher just because of his/her skin color, but I don't think there's anything wrong with preferring a more spirited preaching style or a more lecturing style, or anything anywhere between.
Like on Prayer Call, one of the substitutes when Pastor Jackson can't do it is Min. Shaunta. She's very well liked among the callers. She doesn't raise her voice, she doesn't talk fast or use flowery, deep catch phrases or anything like that. In fact, she speaks very slowly, often pausing at length, and it sounds very conversational. Her style is like the total opposite of Pastor Jackson or Pastor Ryan (another substitute). But one LGMer told me to let him/her know when Pastor J is back because s/he can't take Min. Shaunta. LOL! This person prefers the spirited, charged-up, energetic prayer style.
Both of them reach heaven with their prayers, so it really comes down to preference. To me, there's nothing wrong with that.
