I use ScreenFlow (from www.Telestream.net) because it is fairly intuitive and has all of features I would ever need. It is also made by a company that has strong experience in the video arena and I think it benefits from the development of its (higher-end) product siblings. I want to spend as little time as possible on the technical aspects of screencasting, so that I can focus on my product/service and content. ScreenFlow handles the transitions, audio ducking, custom cursors, callouts, editing, encoding, titling, etc. etc. without making me open up other apps.
