Anyone use aftermarket gaskets for the oil filter housing or intake manifold gaskets? Are they just as good as OE (corrected from OEM)?

BMW gaskets seem to be about 2 - 3 x higher?

I see the following brands:

elring
URO
Hamburg Technic
rein Automotive
ajusa
Victor Reinz

Also, anyone use one of the aftermarket valve covers to replace pvc/ccv system with issues?

Thanks in advance,
