Cometic rear main seal vs...

I was wondering if anyone has had any experience with Cometic rear main crank seals? I just bought one from US ebay (I live in Australia), it was a good price I thought at US$27.50 and only $14.25 shipping. I bought it only because of the name, as I have seen and heard that Cometic make really good quality (and expensive) gaskets. So I was hoping that quality also extends to the rear main seal.

I also have a Felpro here but was thinking the Cometic may be a better choice. I know Superformance are also highly rated (better than Felpro) but was hoping someone could know for sure about the Cometic

thanks
