Question about lightning and circuit breakers

This falls under the category of "something I've always wanted to ask but thought it might be a stupid question.."

I, like many people, try to be vigilant about unplugging major appliances if a thunderstorm is coming in order to protect them from lightning strikes, surges, etc. However, would I get the same effect by simply shutting off the main breaker, thereby killing all power to the house until after the storm passes? In other words, does shutting off a breaker have enough of a disconnect to safeguard any power from a lightning strike from getting through?
