Case back gaskets: aftermarket acceptable?

When I look at the case back gaskets at the various material houses, they usually have a ‘Bestfit’ number, which I don’t know is some sort of classification system, and designates OEM, or is aftermarket.

I’m guessing the latter, so: are aftermarket gaskets generally of acceptable quality, or should one hunt for original? Thanks.

If you find no negative reviews, I would find them to be totally acceptable. Regardless of brand, be sure to lightly coat gaskets with silicone grease prior to install. Good luck!
