Paper is the most natural sounding to my ears. But it lacks dynamics and high volume capability.
To add to TWL's post, I think paper is good for absorbing unwanted resonances in the driver. Better than metal and polypropylene (that's a low end material Epos being an exception - there's always an exception)
