Actually, working with Posette is faster and easier if you are rendering in Bryce. The smaller mesh means quicker export-import, and a big advantage is that the whole body except eyelashes (and hair of course) can be done with one texture setting. Vicky requires at least three (head, body, eyeballs), and it was never logical or convenient to have teeth etc on the body texture rather than the head. This may not seem much, but if you are making, say, a comic with six panels to a page, the time saved adds up and the loss of detail doesn't show at such a resolution.
