For whole pages, generating a diff takes about 2ms plus 40ms to load the text to diff against, rendering a page takes about 800ms. So it's cheaper to use "show changes" by a factor of 20. In fact, we've been considering suppressing the "current version" display from diff pages by default, especially for large pages, since rendering the current version constitutes the vast majority of the time it takes to generate those pages. These figures are averages based on latest profiling, some pages take significantly longer than 800ms.
Now, if only the rendering all took place in JavaScript...!
