When you cook turkey, how do you cook it?

I have tried many different ways. I have slow cooked it at a low temperature for a long period of time, I have cooked it at 500 degrees for 30 minutes then finished it off at 350 degrees, and I have cut it apart (breast, wings, legs) and cooked the individual pieces. I have cooked it breast side up and breast side down.Which way do you think gets the best results? What is your favorite way?
