Working in the industry here's my $0.02, I have great luck with the fiber gaskets along with the standard "ford" replacement drain plug. 14x1.50 16mm head.
Many of the new fords use the integrated rubber o-ring at the base, when they go flat they leak, and for whatever reason it always seems that if the ford plug with the integrated gasket becomes overtightened (even a little) then the treads on it become garbage.
The replacements with the standard changeable gaskets are the most forgiving in our application.
Different gaskets for different cars. The 14x1.50 plug is used in a lot of different cars, with different sized wrench heads. Honda's, Kia's, Hyundai, BMW, Audi, Volkswagen, Mercedes.
In my experiences the 14x1.50 plug copper gasket works good on the Ford Diesels, Mercedes, and BMW. Copper crush works good on the Hyundai's and Kia's. The Volkswagen plug has a steel gasket that never comes off, once it's over torqued, or spread to much it's garbage, same with some Audi's.
Honda's and ford's both seem to love the fiber gasket.
The plastic "uni-gasket" is garbage. (Usually blue in color, with small plastic tangs and several rings to 'seal' against the pan, very brittle)
The copper "uni-gasket" is garbage. (Usually bright like a penny it is a non-crush copper gasket with an integrated rubber insert to make it "universal", the copper doesn't seal, the rubber ends up taring)
The steel "uni-gasket" is garbage. (Usually dull brushed metal in appearance, supposed to work just like the copper "uni-gasket", same BS.)
