Dvavc - Based on cunductivity, silver being the best, I did not bother trying anything else.
Other metals may be harder and more durable, but I consider conductivity to be the most important asset of any metal used in audio applications.
Having removed the plugs from the outlet several times since they were installed, I was pleasantly surprised to find the silver plating had not worn through to the copper, so it must be quite thick, which is good and considering skin effect, could mean the bulk of current transfer is via the silver plating.
Another factor is that when using some other metals as a plating finish requires a third metal to be used as a base on the copper before the final finish. The combination of three metals with differing conductivity introduces yet more barriers to the flow of current.
So I stuck with the simplest approach - silver on copper 👍
