For some reason I have always used cotton batting. When the time came to buy some more, I wanted to see if I could get more loft and after some research came up with a polyester and a wool batting. I bought a meter of both and made did some trials using cotton and metallic fabric.
Now with metallic fabric
The circles puff up nicely. Heavily quilted, this batting disappears to almost nothing.
Now the wool. I am not sure you can see much difference on the pictures, but there is a big difference in feel.
The puff, though not higher, has much more substance to it. It is much more springy.
With the metallic, again solid circles well. There is some puckering on the rings, but that is also slightly due to the plastic nature of this metallic fabric.
Side view show the loft well.
I'm not sure the evidence is conclusive in these pictures, but for me, wool batting/wadding wins hands down.
