What application/location??? It makes a difference.
Rubber intake gasket end seals = junk, ...cork is better here(or a good bead of RTV silicone).
Rubber one-piece oil pan gaskets are the cat's meow, ...cork multi-piece sets I won't use unless I have no choice and a one-piece isn't made.
Cork Auto Trans pan gaskets work the best for me, the nitrile rubber are terrible.
