The composite (cardboard like) ones only leak if installed with too much goop on them because of that same scrubbing action between the block and pan, the goop comes unstuck.
This tech information (SOP) is backed by 27 years of BMW oil pan gasket leaks (I've probably done like 300+(???) in that time) and I know what (and how long it took) to come back leaking again.

I can't stand cork gaskets and I really can't stand RTV either. I have seen more oil leaks caused by rtv then not. In most case's rtv sealer is not applied correctly and this will almost always cause a leak sooner then if the gasket was simply applied correctly with no sealer.
I personally use a non-hardening liquid aviation gasket sealer/adhesive. I typically only use it on one side to secure the gasket to the mating surface.
RTV :down:
