It is not an either or situation. Your past experiences with a traditional clay can be transferred to paper clay. You just have to know what situation calls for the best technique.
Paper clay and its techniques can be a new and invaluable new tool in your "ceramic toolbox." Use what you know to achieve the result you are looking for.
As you can see in this picture, my works in progress are covered with plastic. I have several projects going on at the same time and it's easier for me to continue work on the paper clay while it's still in the wet or leather hard stage.
