Do yourself a favor and look up reviews for your profs before you sign up for their class.
Some times there is only one professor that teaches a particular class that is required to graduate, so it doesn't matter if he has good ratings or not you still need to take his class. This is especially true in some smaller universities.
When it comes down to it, it's the prof. If he's a gifted teacher, it will shine through no matter which medium he chooses.
Some of the best profs that I had were active professionally in their fields a few years before I took their classes, and they each had thier own style from "chalk talk" to in-depth discussions and explanations of what was on the PowerPoint.
