I am finding there is a wide variation in how well fitted mesh fits. Some brands work very well. Others only look good if you stand still. Others have noticed this too. I just saw someone on Fab Free comment that when trying demos you needed to walk around, sit down, and jump to test the demo fully. Good advice.
If you are thinking about fitted mesh, Gaia has one of better explanations of what it is here:
Gaia is working with the ideas of giving AvaStar away free and charging for the tutorials or charging more for AvaStar and giving the tutorials away for free. I have no idea what Gaia will decide. I wish Gaia a profitable business whatever is decided.
