HCH, I too own both Wolfskin and Bucksuede... Your findings are a little different than with the materials I personally own.

My wolfskin is a LOT more supple and flexible in all weather conditions, while my bucksuede tends to be "stiffer"... The wolfskin is probably more water-repellant than my bucksuede too, but the bucksuede's certainly not what I'd call "absorbent" like cotton, either. I'd give the "quiet' edge to the wolfskin sa well -- though obviously, the wolfskin's a good bit pricier.

Without going and quoting all the technica specs, those are my personal findings...
