There are thousands of pre-made assets for Daz that you can just plug and play. In my opinion that's why it's so popular. A lot of those assets are made with Blender and/or ZBrush or some other 3D program. Its animation functions are lacking though when compared to something like Blender.
Basically, it's pretty easy to work with, and there are somewhere around eleventy billion pre-made assets available for use. Many of which are <cough> freely available <cough>
