For me different factory means different quality.

Even if it's manufactered in the same country, I feel like I can never be sure that OE and Genuine are made in the same factory.
Kinda problematic with the pain in the ass oil pan gasket for exemple...

Personal choice.

I "think" when country origin is the same is it safe to assume OE == Genuine.

I learned that OE "Made in Germany" does not always means better than Genuine. For example, my 335d had issues with new OE Beru (Germany) glow plug controller, and Genuine from Eastern Europe solved the issue permanently.

Another example is probably an exception: a cheap aftermarket door handle from PRC was by far higher quality than Genuine one.

My rule is if Genuine markup is more than 20% than I go with OE, assuming same-country origin.
I do stay away from Rein regardless of the cost.
I am comfortable with ZF-branded transmission oil, but I use TPT for engine (I do get it cheap in bulk though)
