I have done both. For years I didn't know how to do anything but square blocks and sometimes with strips in between, but each quilt different because the blocks were hand painted (now embroidered). A few years ago I started watching quilting shows & tried new patterns. I think it depends on what you feel comfortable with and "what" you are willing to try. There are no quilt police - do what you enjoy. For me - today I too say... so many quilts, so little time and I enjoy what I do.
