I've had the step jaws for my VM100 for about a year and finally used one of the inner jaws for the steep-sided bowl seen below. The versatility of the jaws seemed like a great idea, but the smaller jaws are recessed enough to make them only usable if you plan ahead and make an extra-long tenon or do work that fits in there - vases, goblets, or steep bowls.

Your thoughts on this style of chuck jaw?

Here I'm using the smallest of the jaws to grip a tenon.
