I definitely prefer the single camera better. For me it's the simple fact that I enjoy working in front of an audience, but when you're trying to create a suspension of disbelief it's much harder to do in front of audience because they become a partner. Moreso than that, they become in charge of the timing. From the simple, mechanical fact that you have to hold for their laughter. The actual timing of the scene is in the hands of the audience. As a control freak, I don't enjoy that as much as the ability to be able to control it in an edit room.
