The players mentioned that use a metal pick use it on an electric guitar. It would sound totally different on an acoustic.

I'm in the camp of never hearing a metal, stone, or wood pick that I like as well as any Fender Medium.

V-Picks or PickBoy MetaCarbonate 1.0 picks (hard to find) both sound miles ahead of Fender Mediums, to me.

I have all of the above as a collection, not something I use. The last two mentioned are my go-to picks for acoustic.
