Whats the best sleeping position?

I have been doing some research on the best sleeping position and cant decide weather to sleep on my back or on one side. I know that sleeping on your stomach is a no no. Im not comfortable sleeping that way anyway. I read that sleeping on your back can cause your tongue to move back or something like that and will make you more prone to snoring. But I heard that sleeping on your left side putts strain on your internal organs but sleeping on your right side causes heartburn. So whats the best sleeping position?
