Don’t go into a cable section and call it snakeoil or this and that. If you do, you should get banned IMO.
Naysayers don’t take the time to question whether the purity of the conductor matters or not. The type of conductor, the quality of the connectors and the solder process. The geometry. Thousand of different variations. How can a respectable person not take this into consideration.
The connector by itself is a huge variable even though it's just a small part of the cable.
