Comforters and Comforter Sets

Spring is upon us and and we are interested in finding out what people prefer as the weather warms up. Do you prefer to keep the heavy duty warm comforter from the cold weather, or a lighter version of a comforter?  Or, do you prefer to pull the comforter from its duvet cover and just use the dovet covert set itself?  Or,  is a quilt set or a blanket the best way to go?

We are interested in what people have to say about please. You comments are welcome.
