I've only tried Mad Scientist's, I thought it made a huge difference, better than Furutech Nano Liquid, Stabilant 22 gel concentrate or De-Oxit Gold 100% or just newly cleaned plugs and connectors. It's like oil, but man it stays on plugs quite well, never gets dry either. The viscosity makes it easy to get in difficult to reach places as well. It's cheap enough to give it a try. I even used it on the PC's cpu contacts and gpu pci board.
I don't know if there's any time degradation where you need to re-apply after a certain amount of time due to the oil it's suspended in with these products as outside of Stabilant 22 all the oils and things like silver pastes like Silclear seem to degrade over time.
I actually found a website that sells graphene nanopowder ( https://graphene-supermarket.com/home.php ) and thought of making my own concoction mixing it with both Stabilant 22 gel concentrate and De-Oxit Gold 100% solution since they are great contact enhancers in and of themselves.
