I prefer descriptive transformations over slow. If you talk about a long time, the story gets flushed out, most of the time losing the context of a TG story. You either describe small changes repeatedly (i.e. wake up, notice, repeat) losing the changes in a day to day account of life. Or you take long breaks or jump ahead in time to describe changes which occurred in over a long time, but is told quickly (i.e. Two weeks later...) losing the actual day to day changes. I prefer descriptive changes because you can have a distinctly noticeable change for the person changing as well as a distinct difference in their public appearance.
