Turntable mat Sonic differences; cork vs. leather vs. rubber compound


I know there isn't a precise answer for this question but your feedback would be appreciated. There are a lot of differing TT mats out there, all with pros and cons and I've heard both good and bad about most of them. My question is this...

What are your experiences with leather versus cork verses rubber compound mats? I know much of this is relative to the turntable in question but there have to be some general sonic characteristics specific to each. What's your opinion?

(By the way, I'm running a Rega P3 with a glass platter and white drive belt, RB300 arm with and underslung IsoKinetic counterweight, all supported on 3 Vibracones.)

Basically the harder the mat the harder or more harsh or detail the sound will be. Mass loaded TTs do better with softer materials and spring loaded TTs do best with cork. 
..just buy all that are available for sale, then make your own from anything you can.....it still won't be perfect.....there is only one more to evaluate.....
